Hi all
Managed to score one of these today for about $300 NZ dollars
Apparently modeled on a band master.
Released around 1965. 50 to 60 watts. Two channels with two inputs each. Separate bass and treble controls. The Bassman design used a single ECC83 [12AX7] valve for each input channel as used by Fender. Output tubes were mostly 6L6 [also used by Fender], or 7027A in bigger models.

I haven't got it in my hands yet. E supposed to have a massive bass response. One of the first things I'll be doing is replacing the 470nf coupling caps with a more sensible value.

Hey! I have one of those too. Cool old gear. The PTs have excellent load regulation and can easily take EL34s or KT66s or KT77s

KT66 is a kinkless design and can be used instead of 6L6s and has heaps more bandwidth and earlier breakup than 6L6 - think Marshall tones, - but also requires 1.6A per heater (c/f 0.9A for a 6L6). They need rebiasing.
KT77 is another kinkless design but (somewhat like EL34s) are specifically designed for higher operating voltages (500-600V). They also require 2 x the typical load resistance of an EL34, 6L6 or KT66. Good KT77s are getting increasingly rare to find.

Yes it looks liek you could get tetanus from the inside of the cab, but its off getting a spruce up from the local NZ amp guru (who used to play these back in the day)
The little bare screw driver pot at the far end of the photo of the tubes is actually a gain adjustment. So essentially this amp has a gain and master component which is cool

I'm actually looking for one of these at the moment. You still got it?
