classe ca 200 running too hot?

Try checking bias. Should be 24-26mV after warm-up. Mine ran really hot at 39mV. Now it's just warm.

I hope he fixed it,15 years is a long time to live with that problem.

yes LOL..The overheating of the amp was because of the use of Goertz speaker cables which can be problematic with some amps. Sold the cables & eventually sold the amp, Happy ending.

High capacitance speaker cables can cause some SS amps to oscilate. This can cause them to heat up or even blow.

Look for speaker cables with a capacitance of around 35pf/meter or less.

Van den Hul d352 is one such cable as well as NAIM NAC A5 (the lowest I've heard of) and KLE Innovations gZero2 or gZero6 to name but a few.

NAIM amps (which I have) can also suffer oscillation - that's how I heard about it

Hope this helps

I tried the CA200 with some ML Quests, and it had the odd behavior of dimming the lights on loud passages, so it seemed a little different than just underpowered. When I went to the CA300 I never saw the problem again.
