Update: Took my "Sakua" (no 'r') 200T in to an (old) old school guy I found in BKK for the 'no output at all' problem. He couldn't find the problem right away, so spent a few days on it. Changed the 4 transistors, the 4 big resistors, various caps...
But got it working fine.
Cost me 1000Bt (1500PHP) but I never would have figured it out myself.
He couldn't understand me about the small tube jumpers, so I will do that myself... later.
Thanks again!
did you check out if your speakers burned out?
with output transistors burned like that, speakers are suspect...
if your speakers survived and did not burn out, i will call that luck....
was that really the problem? could be after all the relays were
there just to delay the speaker connections and not to
protect them...
just about any 6 volt twin triodes will work here, 6bq7, 6bk7, 6aq8, 6dj8 and siblings, even the 7dj8 will do...
jumper pin 1 and pin 6, pin 2 and pin 7, pin 3 and pin 8, doing so doubles your transconductance and lowers distortion some more...
have fun.....
