Hi

this is mys first post to the forum - tried to find a similar post to no avail.

I live in Australia & have a fender super 210 amp i bought new in the early 90's. It's been gigged a lot & recently I have noticed that the clean channel has very little output compared to the dirty channel - ie when the clean is on 8, it's about the same as the dirty on 3 with the preamp gain rolled right back.....any ideas / hints....I recently replaced all the valves & it made no difference.....it has 3 preamp valves & 2 master valves

thanks a bunch
