RE: Supplementary heat sink?

Posted by KanedaK on September 16, 2020 at 01:08:38:
I used to have the A100 version from the 1990's.
I bought it second hand, kept it a week: it was so hot to the touch (including the potentiometers) that it was barely useable.
Then some day while I had my back turned my stupid flatmate put a newspaper on it and I thought the thing was about to melt... fortunately nothing bad happened but that incident made me return the amp and get something less dangerous.

I've had some other classA amps since, but none that would get as silly hot as this MF amp. Far from it. The way they conceived it is flawed for long term reliability IMHO... so yes, you might want to add some heat sinking if you plan on keeping the amp!
