I have an old 22 w/eq that I bought new back when and I replaced the power switch yesterday and need to know where one of the power light leads connect. One goes to the polarity switch I believe but the other was taped off during an emergency repair years ago during a gig when the power switch broke and was bypassed. I have the schematic but don't see the light. I don't want to guess on this. Also, even though the amp sound real good on the clean channel when using the lead channel is not smooth and the longer it stays on the rougher it sounds. Its hard to explain the sound, but it is not correct. A long sustained note will have a strange waver to the sound instead of a solid tone...any suggestions on these problems would be very very appreciated. thanks, Alan
