Does anyone know a good part number for D11? It's marked 5A but when I search it I get mixed results. I've already replaced:
Q207-Q210 (IRFP3415) Shorted
C31,C33,C35,C36,39 (330uF 63v) Open
C23,C25 (4700uF 80v) Out of tolerance
D23 (Blue LED) Open
While cleaning up from all that I noticed D11.

On the bench it appears to be okay but when I turn it up it starts turning on and off. I think I'm just not giving it enough power. I'm running 100hz with no clipping @ 4ohm and am getting a clean wave producing ~212w. The voltage meter on the power supply is out of calibration, it is producing 13.94v.

For short term testing, a battery or even a jumper pack would help. For long term testing, you need more supply.
I forgot to mention that I ran it like that for ~20mins straight until my power supply over heated.
I really appreciate you Perry. I bought this one broken on ebay about 15yrs ago and I was intimidated for over a decade to touch it, but now I think it's going to work.
No. I just have the 40a p/s with your switch box and just added an old lawnmower battery so I don't have to redo all my radio settings every time I want to play with it.
Just in case you need a laugh tonight. The reason my tutorial was about 15yrs outdated is because my girlfriend of 10yrs left me one day about 13yrs ago. She said "you spend too much time at work and then come home and mess with those damn amps". So I stopped. Now I live on 45 acres, land and house paid for cash, another 5 acres in west TX cash, 2 new trucks paid for cash. She's single, renting a house, two kids no father (I'm not the dad). HAHAHA
All I wanted was a hobby...

I couldn't generate any interest in those switchers and I'd hate to have to work without one. If you have one, it's likely one of about 5 ever built.
During the summer, I hope you don't have to cut all 45 acres every week!
