Lost ch7-ch8 on this less than 2 year old Pyle PT8000CH amp---from reading thread https://www.audiosciencereview.com/...-multichannel-amplifier-teardown.43333/page-4, suspect bad power transistor. Not sure what caused failure. One day good, next day bad.
Any ideas on best how to confirm before I get started down wrong path?
Am new to this forum and newly started audio amp repair as hobby and have a 50 year old amp out of old juke box am working on also, entirely different beast. Have oscilloscope and plenty of tools.
My amp is slightly different than the one discussed in other thread having tear down, reported as same model.
The heat sink on mine has what looks like 4 round power transistors, 2 on each sink. The same reported model in tear down post does not have these.
Advice greatly appreciated.
