Mine WERE--till recently....and it seems that the foam is RAPIDLY crumbling on them. Cones are fine and all else--just surround foam. I WILL check out the google videos. Spiders and VC's all ok--so alignment should not be TOO much of a problem--with the spider intact...right?

well after over 25 wonderful years of service...my Mach II speakers are FINALLY having "wooger" problems. Like many I am sure...the foam is crumbing on all 4 of them. I have never attempted to re-foam a woofer. I can get kits to do so on Ebay...but I am not sure how difficult it would be...

While playing around recently....I stumbled across an article in radio electronics, 1979 issue, april. It described the then-new carver technology of magnetic field amplifiers. Len Feldman wrote it. What was describes in the article is MUCH different...then the way I THOUGHT magnetic field...

I have wondered about this for many years now. Over 30 years ago....I had a small tube amplifier--IIRC, it may had been a VM. It was from a 'shopping find", and I pulled it from the cabinet and took it home, sometime close to thanksgiving of 1984. it used a P-P pair of 6BQ5 amp tubes--not...

I am going to replace the electrolytic cap anyway--even though there is little hum. Over 50 years of service is long enough. Likely I will hide modern caps under the chassis--and I may put a 100/350 or so in place of the 40 uf one--and a pair of 47uf/350 for the two 47uf ones. A 22/450 which I...

Well...this one ALSO works--as-is!! Of course--there is MUCH LESS...worth actually listening to on the radio than there was in 1982. back then...there were a LOT or actual " rock and roll' stations actually PLAYING rock music--all over the FM band. Also a number of instrumental stations that I...

I know this is an OLD thread...but I am posting this because I too...just got my hands on one of these chassis. I spoke about this some time ago--on "your first stereo" thread. THIS was it. It took me nearly 25 YEARS---to finally get one like the one I had in the early 1980's...which got...

Mainly the bigger one are ok. Of the major brands--RCA and Zenith in particular had a FEW nice console amps in their stereos. The well-known "molina" style Zenith of the late '60's with the seperate amp was NOT bad at all. It had large sinks on TO-3 germanium outputs driving a 15" 3 way...

THIS ONE will soon be mine... Pretty sure it has the "good amp" the one with P_P 6BQ5 amp outs. Cabinet is not too good, but not real bad. ALso has the em84 eye tube. RCA 4VF series Getting it for $40, will pick it up next month, after the ETF convention. Already have one like it, do not...

As promised...pictures!! And some NICE pictures indeed!!

And that is the CASE. it was a physical damage unit, and the case was not available evidently. SO, ALL of the electronic components were saved, down to the fans, cables, controls, that 25+ pound toroid tranny and even the speaker connectors!! ALL it needs to be a SUPER DUPER amp--is a case...

I recently acquired a complete hammond L-103 organ, and it looks to be complete. This one DOES use the mechanical tone generator. I was thinking of stripping it for the amp, speakers, generator, and tubes and such, probably selling them seperately. But...would it be better to keep it whole, and...

I guess this makes sense. So in other words...the engine may be "out of it' so to speak, and it is not able to burn the fuel either efficiently enough or fast enough, and simply "puffs", at least for awhile. Then, (usually anyway, unless something is actually wrong..), it "wake up" and...

I am curious about something. Something I have seen a number of times over the years. An engine is rotating on its starter...You can see from the exhaust that the fuel is being burned as it turns over.....BUT...the engine WILL NOT "take off" and "start" running on its own. WHY is this?? I have...

Got TWO of the larger RCA consoles I have long wanted recently. One was the one I spoke about in this thread a few years ago, the VRT--84F 75" long beast. with that RS-263 amp I spoke about. I WAS thinking of just gutting it, but it looks too nice for that. The condition is QUITE good, I...
