I had this problem a few weeks on tube voicings 7-10 then it went away.  I took my amp a friend's house and the low buzzing sound started.  I opened up the mp2 and the capacitor closest to tube 1 fell off.  What's the best method of fixing this?  Buy another capacitor and resolder?  Also, where does the positve and negative connect?

Buy a new one, get the old wires from the cap out and put a new cap in it. Polarity is printed on the pcb.

PCB means printed circuit board.Any electronics store should have these, or online somewhere. (mouser, digikey etc..)

Finally got around to doing it today, and it was easier than I thought.  Everything working fine now.

Thanks!
