I have a DSL401 combo that I just performed a bridge recifier replacement on due to intermittent output. It ended up being cracked solder joints on two of the pins of the old rectifier. I went ahead and put a larger rectifier in and now I have sound on both OD channels, but I no longer have sound on the clean channel. If I turn the master volume and the clean gain all the way up I can just barely hear the guitar. The only thing I can think of that was squirrelly during the swap was I got a bit of a shock when I went to remove the terminals from the standby switch with pliers. I need to open the amp back up to check the bias voltage anyway, so are there any other things I can troubleshoot while I'm in there?
