I Hope someone can give me some advice with this since I'm stuck.
I recently bought a uni t utp 3705s power supply seams like the same as a tenma 72-8700a.
2 channel 0-32v 0-5a.
During a anodizing job I messed up channel 1 it blew the fuse and since then is unregulated stuck at 32v.
Channel 2 is still fine.
I have swapped the power transistors and op amp between the 2 channels and no joy.
Can someone give me some advice on where I can start looking, it seems like a common problem on these units.
Kind regrads
