Hello All

New to this forum. Does anyone know anything about the fisher tube console amps like the 680? I think a few of them were placed in fisher cabs called ambassadors.

Im familar with a lot of the fisher reciever and integrateds and pre amps. But was wondering if anyone has taken a look at any of this ugly vintage amps. The one i have --which is not operational yet-- is a uses a 7591 out put....

thanks all in advance

Mono? I saw some great looking Fisher mono blocks over at Russman's last Saturday but I think they had 5881s........could have been repinned and rebiased from 7591s. Potted transformers painted black on gold chassis, I can't remember the driver tubes.
 
Hello Kbuzz...This is James...I bought a pair of Bozaks from you last year.

The Fisher stereo console amps are nice...but be forwarned that the models you are talking about require a mod to the bias circuit to work as stand alone units. They are all cathode (automatic) bias amps, and utilized the tubes in the tuner preamp as the "resistor" in the bias circuit in order for the output tubes to have the correct bias voltage.

The mod is simple enough...you just have to add a power resistor to the amp.

There not as "ugly" as you think...the stereo console power amps will sell on EBAY for as high as $400...certain models such as the mono 30-A will go higher than that if the are in pairs.

Just be careful when shopping for mono console amps...some of the 30-A's have an output transformer with a lone 2.5 ohm output tap.
 
Stereo and mono console pulls

Thanks all for the replies thus far.

I will need to look at the technical suggestions.

Yes i agree on the fisher 30s. I did not even know they were console pulls. Just thought they were small monoblocks. I like the midrange on those units quite a lot.

Jimmy-which Bozaks did i sell you? The sonora's. Are you the one from SI was restoring alot of units for fun and eventual sale. I really enjoyed those bozaks...but they are flawed and need a sub....

Funny how fisher seemed to have a bewildering array of models both mono and stereo...
 
here a are few pics of a 680

Yeah...I am the guy from S.I. I actually graduated to doing quite a bit of selling of restored tube gear and the repairs are starting to flood in...I cannot believe how many people need tube stuff restored!!!

Yeah the small Bozaks weren't bad...but they got sold to a friend. I have since graduated to several larger pairs of Bozaks...from B-312 to B-313 and now a pair of beautiful 1966 B-302-A Urbans.

Fisher made three versions of the 30-A. Two console versions (one is the aformentioned 2.5 ohm model) and one "component" version that is painted brown and has a cage. They also made a similar amplifier called the 20-A.

Are you still running the 400-C??? Also I saw on AA that you seemed to have gotten your Radiocraftsmen up and running.
 
the urbans rock

jimmy dee

glad to see you scored a pair of urbans...they are one of my all time favorites both sound and style wise...

heck did not know you were doing the restore thing..i have a few items around.....

yes im still using the fisher 400---it has its drawbacks but i keep coming back to its tone.....i have scored a pilot 216a though and await its ups journey.....

the radiocraftsmen continue to be a saga. finally got them back 1.6 years later (from the wacko tech)...his buddy rechromed them nicely....however the electrical work left something to be desired to the point where i coundt listen to them,...

they now are with blackie pagano for assitance....looks like ill be on to 2 plus years waiting for them....and heck they are good but they are not worth waiting that long for....

i mean they are not fairchild monos....or even homebrew sets....

let me know if your accepting gear.....im dangerous around soldering equip and electronics....
 
sent you an email via..Audiokarma's system. If it doesn't come through...email me via Audiokarma or Audio Asylum...I use the same moniker there.
 
Hello: I was following the threads about the Fisher Consoles. Does anyone have information about the Diplomat (III) consoles. I thinsk the model number was D-390. I only have an image of the top and literature:

Thanks for any information,
Roivett

Roivett:

Is that a recent Ebay win? It looks like a piece that sold locally to me lately.

FWIW, the layout looks very similar to a Model E-44 console I have. Is it tubed? Mine uses the 440A and 440T chassis and came with some very nice Bugle Boys and Telefunkens. Sounds nice too.
 
Hey Andyman: It might be the one you are ID'ing. I picked it up from Ebay on Ebay from a gentleman that lives in the Detroit area. I currently run a 1964 Curtis-Mathes with 6BQ5 outputs. I love listening to it. I boxed up by TDL rtl-3's and NHT super zeros (old one's) in favor of the C-M. I have seen some gems over the last few months in terms of consoles. I'm hoping this Fisher D-390 "Diplomat III" is worth the trouble to have some friends in the Dteroit are pick it up and store it for a few weeks. I'll be travelling from Alabama soon to retrieve it.

Later,
Roivett
 
Fisher Custom Electra Model E-492

I acquired a Fisher Custom Electra Model E-492 console this past weekend. It's a chassis 21 unit, everything works, and the wood is in almost perfect condition. The turntable is a Dual 1010 with a Stanton 500 cartridge. The FM reception is very good.

This is a topic near and dear, as my affection for vintage Fisher units began last year when I salvaged the 481A amp and 590T/MPX65 preamp/tuner from my inlaws' old Electra E49 console. They were moving and had not played it in years. It needed some work, but the amp and tuner/preamp are now mounted on a nice Mapleshade platform and they listen to it through a sweet pair of Fisher 75 speakers. The hollowed-out cabinet remains, while we try to figure out what to do with it. It sounds great.
 
Fisher 31-R chassis and nuvistor questions

Bringing a dead thread back to life, I recently picked up a Fisher console unit, specifically a model 31-R chassis. It looks very "tube like" but appears to be all transistor. Well maybe all transistor, there are three small cylinders next to the tuning block which could be nuvistors. Below is a photo of the unit. It is going to take some work to swap out the speaker connectors for binding posts and it will require a general clean up and possibly a recap as well.

Is it worth building a box for this unit?
Perhaps even more important, Are all nuvistors the same?
If these are nuvistors in this unit, will they work in a Fisher 600 front end?

Yep, those are the three nuvistors. I had an Ambassador unit I picked up off the curb and parted out to a guy overseas and those were 3 specifically requested parts.

Now what the heck a nuvistor is and what it does, ya got me, but those ARE them.

Good Luck,
Andy
 
Nuvistors

They were itsy-bitsy metal tubes developed at the twilight of the tube age (or the dawn of solid-state--your choice) for VHF & UHF use. Very close electrode spacing allowed use at considerably higher frequencies than miniature tubes of the era, plus they were pretty rugged. Quite common in tuner sections of 60's-early 70's TVs.
 
A Nuvistor is just a really small metal tube. They were high-tech in the early 60's. Very quiet and stable, very good for front ends. Probably they couldnt get similar performance from solid-state at that time.

Like other tubes, there are a bunch of different types, different filament voltages, and so on. The two most common are 6ds4 and 6cw4. They unplug like ordinary tubes. There will be numbers on them.

Nuvistors are RCA's last generation of vacume tubes. They were used mostly for low power high gain uses. In consumer electronics they were used as an RF amp/osc in tuners and color televisions.
