I have made some mods on my amp, 3 prong plug, Mercury Magnetics output transformer, 10 inch speaker mod, 5V4 rectifier for a slower warm up and a 5881 for output. When I play the amp, all sounds great and functions fine until the sound fades and drops out. When I look at the tubes, all of the filaments are lit except the output tube. The problem seems intermittent. Any ideas?
