Maaartiiin!!! Where are you? I need your help...

So where is the sound of my amp? Anybody knows?

Hej Pavel,
check all wiring.
Ground fail at in / out section?

Hi volvodidi.
Ground is fine. Thanks -
You must follow the audio signal through the amp, from input to output. Check the signal behind the preamp section.
People how made dangerous high voltage projects should know how to do this... hopefully. -
Hi Pavel,
did you check the output transformer (w/o power)? What is the resistance measured at the output plug (8 ohms output)? Do you hear any noise (hiss) from the speaker when the amp is turned on?
Regards,

Hi MAD, glad to read you))
So, resistance at the output plug is 1.5 Ohm.
I dont hear any noise, when the amp is on.
And what is it w/o power?
Thanks for help)) -
Sorry for disturb guys, it was just BAD speaker plug jack:cool:. For now everything is good. No... very good!
No background noise, just guitar. Sounds magnificeint!!! I am very pleased with the amp)
Thank you very much and good luck. -
Great, thanks for the update!
Regards,
Have fun,
Martin
