QSC 1200 Amplifier Fix and Recap

Описание к видео QSC 1200 Amplifier Fix and Recap

This is a QSC 1200 Series one amplifier I purchased off of Ebay. It had a problem with the bias diodes which caused the output transistors to run hot. I saw 1 volt of drop across one of the the bias diode, so I replaced all 4 of them. I also replaced the 2K bias resistors as these are known to fail, and replaced all of the electrolytic capacitors except the power supply/speaker coupling caps.
