re: AA-100

Very rich sounding amplifier. Found one on Ebay, but needed lots of TLC. New caps, new tubes and lots of cleaning. Major falw: Output tubes get extremely hot, baking the board, causing traces to let go. Best to run without the cover. Let the heat flow up and not build up inside. Not a bad amp at all for the analog listener.
