Alright so yesterday I was playing guitar and then after a few hours my amp's volume gradually declined to almost nothing. I turned it up and it barely went anywhere, its a 45 watt tube combo, so it gets loud. I was concerned but I put it on standby then a while later i plugged in and turned it on and it seemed to work ok so i turned it off. This morning I wake up, set up my pedalboard and stuff, plug in and its working fine. Then the volume decliens again, i turn off my noise gate and it seems to be normal, i shrug and continue playing. A short while after (less than 5 minutes) I hear my amp sound really sort of fuzzy or crackly, i turn off some pedals and stuff and its still really buzzy, and quiet, i switch to the clean channel, same thing, i push all the buttons and everything, its not gonna work. I turn it off and log onto PG. I replaced the power tubes in januarybut i dont know when the preamp tubes were last replaced, i normally play at low volumes.. about 1 on the dial sometimes 2 tops, if anyone knows whats wrong please reply.
THhanks in advance
