Beware the bias! I had a Kenwood KR-5150 way back in the day. When I got it, outputs on the right channel were DOA. I got OEM replacements, also replaced the drivers. The beast worked fine and sounded great, but after a few days those same transistors shorted. Icon_sad

Turned out that the bias pot was intermittent.
