Thank you! You can learn everything and you will restore stuff. Whenever we can recover something that was trash it makes the world a better place. And electronics are out of hand so it is great having more technicians.
Pls sir if you can help,,,,I have been working on a hartke head Ha3500,,that was vandalized,,,finally mounted missing components following the schematics, preamp works fine now,,,but for the power amp section relay won't click so no sound output,,,,yet transistors are ok,,power supply looks great....what can I do?
I'm not familiar with the amp but if it was in bad shape, it's very particular for that device itself the damage, try to continue troubleshooting for problems. If there's an IC that controls the relay and protect mode, you can start from there and any shorts or small alteration on the board, traces, ground, for example, could trigger protect mode as well.
Cool video sir..gives me more confidence as an upcoming technician.
