using 12AU7 on 34
#10

Hi All;
Morzh, Thank you for the more detailed explanation..
What about the two Audio transformers, the input transformer is fed by a number 30 tube fed by a 135 volt B+.. (I think I just answered my own question) then it goes to the number 19 tube.. the Output of the 19 tube goes to the Output transformer, which is also powered by B+ of 135 volts, thru the center tap.. So, just to verify, I could use it at 135 volts or maybe go about one half to one third of that figure to test each transformer ?? The transformer that is center tapped I would use half of what I would use on the other transformer, correct (Assumming I would be applying voltage to one side of the tap) ?? Once I (hopefully) found each transformer to be good I could put 135 volts to the one side and then find out the correct voltage for the other side of the transformer ??
THANK YOU Marty
