My AVT50H 2000 still working fine since... well... 2000. I'd actually recommend it but i don't want the prices to go up or get rare. Maybe all the people you know with one aren't nice people, or at least, to their gear. Fans- Noctua. You're welcome.

If it sees a shorted speaker or has a speaker load connected while powered on, it will eat the transistors. I put some Noctua in a BV300h. Do you have the compatible model number for this amp?

Continuity? I don't understand what happened there... Is there potential for ground on the back side of the chip?

Yes the chip can ground out on the heatsink. Theres a mica insulator and insulated hardware to keep this from happening.

You bet. If you plug a speaker cable in while the amp is on it will blow the chips up.@@outerbanks854

In my experience the transistors are not really meant to push distorted audio and can fail. There is alot of information about this already but I wanted to make a video to help anyone who owns one. If I hadn’t of gotten it for free I wouldn’t own one however. I got this one for free because someone plugged the speakers in after turning the head on. The combos are not usually damaged this particular way because the speaker is always plugged in.
