50 watt amp project

Hey Rick

It sounds like you are doing the step by step testing that TUT3 says to do but you missed a step. For me that was a big lesson "baby steps" cuz I used to blow up stuff when I built it and just hammered on the power

Did you connect the power amp to the PSU while it was all still just out of the box on your bench? You coulda checked voltages on the amp part to make sure things are cool there. Must be something in the PA or the wiring between the two parts since the supply already worked.

That's my guess.

Thanks for the input Nauta, very much appreciated. I had hooked up the plate and heater supplies from the PSU but I didn't have the OT hooked up at the time. I borrowed a friends drill press and got busy with drilling the front and back panels and the bottom plate ect. The problem I was having at the time was the whole system gets a little out of control with the power transformer, power supply board, PA, and PAF board. The PAF board is especially small and light. The connecting wires were lifting the boards and everything was a bit out of control. I connected everything to the bottom plate of the enclosure and hooked up the OT, then finished the rest of the connections, yes, I should have tested when I hooked up the OT, before putting everything together. Maybe time to take it out of the box, easier to see everything, and go over the PA and OT connections. Thanks...
