Weird 5150 combo problem

[Vincent]

Hi JerryP, I bought a 5150 combo two weeks ago. The previous owner retube it with JJ's power and preamp tubes, they are about a year and a half old I was told.

It sounds great and it was everyday and today morning. Later in the afternoon, when I turn on the power, the red LED isn't lit. I turn it off and check to see if I plug in the plug properly, I did. I turn it on again and still no LED.

I then look behind the amp and weirdly enough, the tubes are working. So I thought, no biggie, probably the LED isn't working. I proceed to turn on the standby switch and guess what? No green LED and what's worse, no sound.

I checked my cables, tried my guitar in another amp, did the effects loop thingy, tried a different input and still no sound. I am getting really worried here. I can hear a faint hum and popping sound from the speaker even when I am not playing the guitar.

Also, I am not sure if this is normal but the when I switch on the standby switch, the powet tubes seem to be glowing very bright, probably way too bright cause it smells like it is burning. Is that supposed to be normal?

I also took the chasis out and everything seems fine inside, no broken solder joint and nothing seems to fried.

I also checked the speaker and it seems fine too, no loose or broken wiring.

I hope it's nothing serious and hopefully you can offer a solution. Cause I am in Malaysia and it is going to be hard to order parts from Peavey.

Thanks.

Whoops, forgot some other stuff, the channel switching doesn't seems to be working and the amp isn't responding to the footswitch.

Sounds like you have a blown fuse inside the amp. More than likely caused by a bad power tube.

Thanks man, probably it's time to retube.
