I have an early Beige Thunderbass amp with a separate cab for the speaker. It has a 15 incher in there.
The head uses 2 8417 output tubes and as far as I can tell 1 12ax7 for each channel and then 2 tubes for
what I would say is the pre-amp section. It located between the channel 2 board and the output tubes.
Im trying to find out what tubes actually belong in this section. One appears to be a 12ax7 but the tube
closest to the output tubes I cannot read anything on the tube. I've been to Prowess and browsed the schematics.
I didn't find the right solution from the Internet.
