My Valvestate VS65R only puts out about 5% of its original wattage. It gave a pop noise a while back while I was playing  at 70% volume and fell silent while I was testing a new capacitor. I found a set of circuit boards and transformer, installed them with a new tube but only get the small amount of sound even with everything turned up. I tested it with different combinations, transformers, boards, tubes, speakers, guitars, cables, but no luck. Any help on what the cause could be, or how to troubleshoot would be greatly appreciated. Peace and Rock On!
