I have a 405-2 that when changing capacitors I found that c10 had been put in the wrong way in one channel. The amp works but the sound seems slightly lower on that channel or a lower mid range. Its quite strange. Any suggestions as to what i should check to fix this greatly appreciated.

Did you turn the cap around to the right polarity?

All new caps. Sounds great apart from that problem.

Are the values of R30 and R31 still correct?
