I bought this amp and rebuilt it. New power supply capacitors & a relay to switch the 600 volt secondary. Palomar had the tubes drawing B+ continuously- not good. I had four new 6LF6, driver 6LF6 tubes were like new. Anyways on low drive I could get only 300 watts out with a swing to 350 watts. Radio dead keyed 4 watts and swing to 16 watts. To have any forward swing on the amp I detuned the driver circuit and it dead keyed 200 watts to 350 watts. I think this amp is a dog. I was expecting 500+ watts swing on low drive. I did sell it & buyer is happy- go figure.
With two 6LF6 driving four 6LF6 it should make more power. B+ was around 850 volts. Is this amp simply a dog or what?
