Amp Notes

These are important and sexy notes from Scott Fitzpatrick about my new Celtic Edana amplifier:
Regarding the Sovtek inverter tube and the difference between it and the JJ which the amp came with (and unfortunately which showed up DOA):
It's really hard to get a picture of a band in performance which includes everyone.
"Check your bias. Should be between 36-40. Adjust by ear in small difference. Bias test points under chassis. Set multimeter to dc volts."
I also went gushing on and on about how great an amp it is and his response was:

"It's one of the most incredible circuits ever.  True definition of classic.  Best part is, you can drop 6L6, 5881 or EL34 tubes in there with a rebias.  (FYI, el34's change the speaker out ohms...email me if you decide to ever do that)."


These are important notes for me to retain. Keywords are "bias", "rebias", "Edana", "tube".
