My amp losses volume after biasing
Hey guys I'm having problem with my amp., I've changed tube on my amp, then after that I biased it to make it hotter (about 75 mV) before it was 64mV..it was fine and sound good after a couple of days..then I stop playing it for about a week or so because of the holidays(went out of town)...when i plugged it today it suddenly have this loud hiss and has a very low volume..can you help me find the culprit..I'm thinking the tube, but its relatively new..tomorrow i will put electrical contact cleaner and see if it change anything..hoping for some advice..TIA:)
