| Peavey 6505+ blown fuse F1 http://www.schematicheaven.com/newam...ey_5150-II.pdf Amp stopped working....no sound, standby lamp not lighting. Fuse F1 (2AFB) was blown. I replaced the fuse, everything powered up fine. I played my Ipod into the input, output into a hotplate set to 'load', ran it at high volume settings for 20 minutes.....the fuse held, and all seems ok. what would cause this fuse to blow? |

Dying (maybe now dead) power tube. Are off of the output tubes glowing & warm? It is possible that a heater failed & caused a temporary problem. If the leftover pieces inside aren't touching anything it could power up fine (just not sound so good, you're down a tube). It also could have been an arc in a power tube that blew it. Problems with the OT or any connecting / disconnecting loads while the amp is live could possibly do that. If that was the problem there may be no permanent damage. |
