Mystery Mystery Scott "Custom" 6BM8 Integrated???Anyone??

Kenny

Active Member
Howdy:....On a recent road trip to a friends we swapped some speakers,and I picked up a Scott "Custom" tube integrated with 6BM8(output tubes) he no longer had time for.Once I got home & looked it up I found its not H.H. Scott,and I found nothing on their website about it?...I didn't realize Scott was really H.H.Scott..The only identifying characteristics is it has a Musical note through the letter "O" in the Scott name on the faceplate.Has a really beefy little power tranny,as well as the outputs are good size and are mounted diagonally on the chassis,so look like diamonds top side.The chassis is only only 13 wide,seven deep and 5 inches tall..On the faceplate there are dual tone controls for bass & treble for both channel one & two..Blend mono/stereo switch,and the Master Volume has to be pulled out to get loudness feature to kick in..There is also a phasing switch on left side,and norm/reverse switch on opposite side of faceplate?..My tech looked up the power tranny number TP 1023, & Outputs 10...1006 and came up with nothing?...Anyone ever came across one of these rarities?..I purchased it fairly near the Canada/US border so thought it may have originated in New York.There are rivets on the chassis so doesn't that mean a factory unit vs screws when its a kit?.My tech is going to have a look under the chassis this evening or tomorrow to see if the make of the caps may identify it and to see if he can revive it?..I looked underneath and no schematic under there like Stromberg-Carlson used to do,plus saw a few new caps.My friend says it sounds distorted in one channel,so power supply,maybe??..I just couldn't pass it up,its compact size is perfect for my stereo shelf Pond patio/Living room Seasonal systems.I figured with all the neat little Chinese 6BM8's being popular now a days and 6bm8 tubes still being made it was worth a go to get it going.My friend figured eight to ten watts.Its currently running 4 Sovetek 6bm8 outputs,1-6cA4 rectifier,2 12AX7(ECC83).It has two phono's one is ceramic,plus there is a tube that says Philipps mini-watt?...thats all I could find on it..Anybody got a clue what I have here???Its an interesting little output tube when you read about it and seems its has been given a bit of a bad rap as in its earlier life it was used primarily in old TV's and those small portable phono graphs I remember my cousin & me rocking out to in the fifty's...Appreciate any info or other 6BM8 opinions/DIY's with this interesting output tube,as I'm really looking forward to hearing this.Sorry no pics as our camera is currently sending home beautiful pictures while its touring Europe with my Son & his girlfriend...lucky little bugger,lol..Kenny..

There is some company called Scott out there. Don't know anything about them.

H.H. Scott did make one amp that used 6GW8 outputs. Very similar. Usually, they use one of the triode sections of one of the tubes as the AF amp and the triode section of the other tube as the phase inverter.

Allied Radio, Knight-Kit had an amplifier with that configuration as well. That tube is about similar to a 6V6; around 10-watts RMS per channel. Not bad, but you need either efficient speakers or a small room. But, it still is vacuum tube and that is what counts right?
 
EH Scott was an older company than HH Scott - most of their best products were in the 1930's - one connection is that HH Scott built the noise reduction add-on for a post-war EH Scott system. Scott Radio labs was the last name for EH Scott - long after EH had left - and it appears that they sold relabeled TVs and audio equipment. I have seen a few examples of the Stromberg ASR-333 relabeled as Scott. Stromberg used the "161..." prefix on transformers, so this isn't one.

My guess is that the Calrad SA-30 will be similar.. this could be Japanese made. I have a scan of the Sams folder for that at home (I'm on vacation right now) There's info on one version here: http://www.triodeguy.com/calrad_sa30.htm - I had a version that had separate tone controls for each channel. Leaky caps are the most likely reason for distortion - a certainty if it's Japanese-made...
 
EH Scott was a very high quality manufacturer, and their stuff is impressive and collectible. I have an enormous radio (much of their line was enormous radios) which is late enough to have the current FM frequencies, so its definitely post war. Oddly enough it was owned by a Pioneer executive. Even odder, it was my wife who bought it, not me -- the only audio item I have not thought sensible, and the only one she has. But we have never fired it up. Some day...
 
EH Scott ran in pretty good company back in Nov. '58. They also built consoles. That wouldn't be your integrated there, would it?

Wow you guys are the greatest....The Audiokarma Vintage Audio Detectives!.Whoa! I just read the above reply after I posted this and see Tom mentions they were built by Stromberg!!!Wow!!!Anyways here's my thread!!.I have to dash off to do my Honey Do list,will check in tomorrow....I really appreciate this,as I enjoy researching a piece of audio equipment almost as much as listening to it and restoring it,so thanks "all" for taking the time to respond to this 'rare' integrated.The Red 1(sorry I couldn't find your name),that most definably is the 'Scott' name Logo with the Musical "note" through the "O" so that certainly helps identify mine as a Scott,plus it mentions Master Volume Control in the literature as well,and mine says Master Volume too.I think its safe to say its a "later" EH Scott,maybe early to mid sixty's???...My knob layout doesn't look like the one in the picture literature,but thanks so much for posting the old literature,it helped nail the name "Logo" bang on!.If you have any more pic literature,mine has a Blend(Stereo/mono) small tuning knob,same size/shape as the tone control knobs right smack in the middle top,then below that it has the twin Tone Control knobs on each side of the faceplate.....something to note...these 'original' knobs are smaller(in diameter) long thin knobs and stick out of the faceplate enough to get you fingers around them,just like the knobs you used to get on old tv's for tuning in the "Contrast',etc.....maybe thats not a coincidence,as Tom mentioned they later on built relabeled TV's & Audio Equipment,plus 6BM8 tubes were used in TV's as well,so I'm almost certain we have found it,just a slightly later model,maybe their last model,who knows,so I'm thinking that I have a pretty rare bird here!.A survivor!...Unfortunately its also missing its cage,but I know a sheet metal guy that can whip me up a nice one fairly cheap,if it checks out ok,and I decide I want one.I just dropped it off at my tech friend last night and forwarded him the info you guys have found so far.I am interested to see how close the Calrad models are to its circuit,especially the Calrad Tom mentioned he had with the twin tone controls.Thanks again Tom,for the valuable info and links.This EH Scott is parked temporarily till my tech friend finally gets to finish installing an Eico ST40 output transformer into its restored chassis!!.Took quite awhile to find another output tranny reasonable,but thanks to another Canuck Audio Mart member I finally got one.It sure does look nice under there now with the bright orange drops,new red resistors,new tube sockets,speaker connectors.Wow its looking real,real good,and the top of the chassis is all shined up with new JJ Filter cap & all the transformer casings re-painted..This one was a "real mess" when we got it shipped from Nova Scotia.Thought my tech was gonna make a run for the house but he said he had seen worse!!!..Between the salt air and the dirt-n-dust.Well you can picture it!!..You wouldn't recognize it now.I am going to use it as an amp only(it can be changed back very easily)with a custom tube Line/phono pre-amp my tech tube phono my tech built and tweaked the phono with scope for many years.Can't wait to hear it!...Tom I see you are into Stromberg ..This Friday I hope to have a listen to an older Stromberg-Carlson integrated that was modified/based on a Steven Bensch circuit to accept 5881(originally 6V6) output tubes,14 watts Triode wired,using above pre-amp this Friday through my Altec 19's...I have never heard the "Triode" sound so should be very interesting!!...Enjoy Your Music...Altec Concert Kenny.
 
Back in the late 50s, there was a lot of litigation between the older Scott (remnants from the legendary E.H. Scott) and relatively newcomer H.H. Scott for the use of the brand name "Scott".

The older Scott was in dire straits financially and H.H. Scott was booming in the new business of component Hi-Fi.

Eventually, Hermon Hosmer (H.H.) Scott won and the older Scott had to rename itself to "Ravenswood". It died quietly by the mid 1960s.

You can tell that around 1962 or 1963 , the H.H. Scott company dropped the H.H. from its name, identifying itself simply as "Scott". They had won the litigation battle.
 
Crooner,thanks so much for posting,very interesting history to EH Scott's,sad,slow demise.I appreciate you bringing this to light,I would have never known if you hadn't introduced this... " Ravenswood "...I really like that name,it reminds me of beautiful rocky,deserted place I used to happily enjoy hiking near my Family's old oceanfront home on Vancouver Island,which seemed to have more than its fair share of those big,intelligent,beautiful birds following & watching me from high above move about the rugged park,making their clicking communication to one another.Do you happen to know if E.H Scott actually made any amplifiers under the "Ravenswood" name,or did the litigation ruin his life and livelihood?. If this little amp gets revived the way I'm hoping it will,maybe by Christmas,and sounds half ways decent,I am going to get a "Custom" cage made up for this,and now after reading this I will get a little plaque made up engraved with that name.Interesting how H.H Scott also faded away as well.An absolutely perfect way to finish it off this little project,thanks to you!.....

You should see about getting that guy fired up. If its built anything like the 30s Scott equipment, you may be pleasantly surprised. The stuff they put out in the 30s was extremely well built, and also extremely expensive for depression-era equipment.

here you go, a window into the peak of the original Scott company. 48 tubes, and a 2 channel 50 watt audio amp in a bi-amp config.

Wow!!..I have never seen anything like that before,and am pretty sure I never will,but thanks to the internet its come to our attention again!.That is absolutely Stunning!.Now,thats what I call a Receiver! It could pick up station's all over the World!.Wow,I sure wish I could have heard the Green Hornet on that one when I was five!.Talk about built to last forever too.I wonder who ended up with the one that went to Santa Barbara? Can't see anybody putting that out with the trash!!!.Not that you could exactly carry it away at 620 lbs!.And I thought my Grandpa's huge wood tube Radio sounded real good with its fifteen inch speaker. E.H.Scott certainly was a high end company in its Heyday.The Stradivarius of radio receivers.So True!That was the Holy Grail of vintage tube radio's! Its a work of art,inmhop,plus a beautiful audio piece and excellent restoration story.Thanks to you I now know where the "Ravenswood" name came from.It was the Avenue that the E.H Scott factory was located on,and get this,this is the real cool part,old E.H retired to Mt Tolmie,in Saanich on Vancouver Island,close to where my folks lived in Sidney.And to think I probably went hiking near his house,and would have never known......Peace & Harmonies..Altec Concert Kenny
 
Kenny, I believe I have the same Scott chassis you described. Im needing the schematics to relocate some wires removed from a can cap. Did you find any info on this unit?

Hey everyone,yupp still kicking,I'm originally from Vancouver Island,we pop up like Magic Mushrooms,every once in a while,usually the Fall.

I've just retired,some Health issues in the Family,plus had some trouble with security issues logging in,so kinda parked AK for quite some time,now seems I've some how made it back on!

sooooooooooo,regarding the above 'so called' mystery Scott Integrated amplifier?

1st,Doug,yours is identical to the one I previously owned with exception of missing knobs,mine had no cage either.
Above thread History was all I could find,'Anywhere',so for sure very rare indeed!

2nd,called person I sold it too,he wants to keep his,so there are now 2 we know of for sure!
.
3rd,contacted my Tech friend to see if he still has or even had a schematic?
.....,No,he didn't/doesn't have a schematic.....and said......"That is Not an HH Scott"....his owrds,adding,......"Note the Musical Note in the O in the Scott name on face plate"...,so I'm thinking,a strong possibility its a knock off from who knows where,possibly Japanese(Calrad) as mentioned above,that would be my guess?

Most Importantly, I remember him, 'Strongly Recommending',gutting the Power supply can or(2 PS caps?) can caps,and re-stuffing them with new caps.
Of course I agreed wholeheartedly,and he did replace PS caps,plus a few others,and I'm still alive,to write about it,ha,ha..

4th,seem to remember' 'Very Lethal' amounts of electricity involved with that Amp's old Can(or other?,Large caps,which of course my tech replaced,made Safe.
Maybe someone disconnected that cap for a reason,me,I'd take that as a Red Flag?

If it were me,I would change power supply caps,before I even thought about hooking anything up,unless you too are a tech or know someone who is capable/qualified,not trying to be a dick here,just saying better to be safe than sorry.Worked for 32 years for me at London Hydro.

I do remember that sounding excellent(in my opinion) with 70's Vinyl,and I had fun with it,pairing it with some D.I.Y Open Baffles using vintage Isophon drivers...I've moved on to EP Open Baffles as my main speakers.

I'll contact Doug personally about above safety issues,regarding this piece as well,nice to be back on AK.

Hope this helps anyone who by chance comes across,any old tube gea,and wants to Listen to it...
