Thanks, Edcor is new to me. Apparently the model for this SE amplifier should be:
CXSE25-8-5K
Single-Ended Output Transformer
25 watts single-ended output transformer, 5,000 Ohms to 8 Ohms.

Best regards from Argentina

just finished building this amp, and need a resource for trouble shooting. Is there any general values and procedures that I could refer to, in tracing down the problem. I follow the audio signal to the coupling capacitor and then loose it.

Frustrated

In the original Boozhound 6V6 Primer Tube Amplifier article it was used a 275 volts secondary transformer to obtain about 250 V B+ in the output stage. The power supply drawing shows 175 V.

Something is wrong here, usually the transformer are specified in RMS values. I need 200 V RMS in the secondary (282 V peak) to obtain, with the chosen rectifier (5y3 before PI filter) about 250V to feed the circuit (0,9 of peak value).

Do you agree?

Thanks, best regards
