News about E-303 temperature
I found online the service manual. And i dare to mess with the bias adjustment. The temps are now about 43C with a room temp of 28C So happy! |

Good job. Will contribute to a long & happy life (for your E-303).

Normally, it sets the bias on the output transistors (power output stage). However, without actually seeing the schematic I can only guess. If the bias is too high they will be running with too much current, which generates the heat. That's why Class A amps run hot. Always on, even when idling. They are 'big' amps (for the large heatsinks, transistors, transformer size, etc.), to safely allow for the higher current (heat) compared to Class A/B. Many folks prefer Class A, but I'm generally good with our Class A/B.

Don't think we do that here, but "the other" forum (Audiokarma - can I say that here?) has a listing for same. Think the DIY (do it yourself) forum also supports same.
