I have a homebrew 45 amp made by a hobbyist that i've been enjoying for a few months now. It uses the 45's along with 4 417a input tubes and a 5v4g rectifier. Just today, I turned on my amp and the right speaker started to make loud popping noises. I quickly turned it off but the popping continued while I turned off the amp. I put the amp on a few minutes later and now there is nothing coming out of the right speaker. I tried switching the input and output tubes but there doesn't seem to be a problem with them. Then I switched speaker cables and indeed the speaker is fine but the amp's right channel has no output. The only thing I didn't do is change the rectifier since i don't have a spare. Even though this is unlikely, can a bad rectifier cause the loss of one channel? I think it's something in the amp and in that case i would have to bring it to my local tech. Otherwise if anybody can troubleshoot this for me that would be most helpful.
