The amp is a ValveKing 2X12 combo, I traded it from a guy without trying it first and got it home not working. It has power and everything but when I got it 3 power tubes were glowing blue and the sound was no louder than headphone with the volume at max.

I just got new tubes for it and installed them about 10 minutes ago, I figured this would be the problem or at least a good thing to try. Nothing. Same thing as last time (no volume) but now I noticed a burning smell coming from the amp. It also has a crackling sound when you first turn it off standby. What should I do next? I'm heading out to buy a fuse just in case that may be another issue.

I also posted this in the VK thread so i hope it's ok to post this here as well, just didn't want the question lost in the sea of posts in there.

renound for its habit of turning off and never coming back on. alot of people have that problem i hear. if its not the fuse i dunno what to do. and you mentioned the burning smell, a guy recently had a similar thing and found out it was infact his cab, so check your speakers.

I can't take it back to the guy, I tried contacting him but he wanted me to drive 4-5 hours maybe longer to take it back where he lived, I had a feeling he would break what I traded to him before giving it back too so I just didn't bother, I figured it would be a good learning process to fix it myself and so far it has been.

I'll check the speakers but I don't think anything is wrong with them. I had to take one out to get to the pre amp tubes and had a look over it, seems ok and the wiring wasn't bad but I'll have another look and report back.

I changed the fuse and nothing different, the speakers are wired up properly and everything too. I also checked with another speaker so that's not it.

Is there any specific way I can test the pre amp tubes or will I just have to rotate them and see which one is dead?

Sorry dude but you got a VK. They tend to be pretty unreliable. You should take it to a tech rather than playing home doctor.

+1 amp surgery is dangerous. my guess is its a power tranformer. and just cause you speakers are wired up does not mean they work! bring it to a tech and pay the price for your mistake.
