Premier 88 Musical Instrument Amp
#3

Hi TV Man,

Sorry, I did not see this post till now, thanks for the reply. At some point, I need to dig this up and photograph it. It should be my next project, but I have car work to do, a trip from Long Island to suburban Washington DC to attend a funeral and other pressing things. Currently 18 degrees here and is supposed to go down to single digits with snow and ice tonight. Now I know why bears hibernate.

The Premier is definitely a cool looking amp. Not very powerful, the output stage is the equivalent of 4 6K6s in parallel-push-pull. My guess is under 25 watts, but that was pretty big for the time. Back in the day, 2 first gen 6L6s didn't put out much more than about 25 watts. With 6L6GCs, at max plate voltage, you can squeeze out 65 Watts in Class AB2 with fixed bias.

I think that RCA used 807s in some of their theater sound systems. I think that 2 were recently advertised on eBay. There was someone either on the Phorum or on the Antique Radio Forum whose tag line was something like "King of the cold cathode 807". Per the RCA Spec Sheet, if you drive the heck out of a pair of 807ws i Class AB2 with 750V on the plates, you can get 120 watts out of a pair of 807s before they go "cold cathode"
