I have a Silverface Twin Reverb that I plan to replace the 100k plate resistors in to get rid of some intermittent static/"bacon frying" noise. I was wondering if there are any recommended mods that I could do while I'm in there, to make a very good amp better? AA270 circuit By jazz tone I'm thinking Pass/Montgomery/Burrell rather than Stern/Metheny. Currently everything is stock except for replacing the electrolytic caps and converting the bias balance to bias control. I want to keep the cleans as clean as possible so I assume "blackfacing" it isn't the answer. The amp is set up with two Weber Michigan speakers and currently TAD 6L6WGC STR tubes. Any suggestions, tips, etc are appreciated.
