Need HELP Repairing a Tube Amp!

[MetalMatt243]

Hi Everyone,

I own a Laney LC30-II Valve/Tube Amplifier. It is an amazing Amp and I sadly/stupidly sat on it for too long on it during band practise (covering the tube vent) which has led the amp's sound to cut out and to have no apparant connection to the speaker (overheated?). All the lights light up fine and it looks like it should work, yet no sound at all!

I mainly tinker with guitars and have never worked on a tube amp before. Can someone point me in the right direction of how to fix this? Is it a common occurance? Is it an easy fix solution?

Any help would be GREATLY appreciated!

You can try a tube swap, but other than that, this is probably not the amp to learn amp repair with. If you want to get into that, find someone who can stand over your shoulder and walk you through it.

You can check the speaker cable from the amp to the speaker. All amps have these, even combos.

You can try a tube swap.

Beyond that, take it to a professional. DO NOT try to repair it yourself, because if you don't know what you're doing then you can DIE from electrical shock. This can even happen if the amp is unplugged and turned off. There are parts in a tube amp that will store a residual voltage for weeks after it's been unplugged.

First, be absolutely sure your cables are good. Check the HT fuse if it has one (not familiar with Laneys). If that's not it, try gently wiggling each preamp tube while the amp is on, listening for loud crackling noises. Do the same with the power tubes. No good? Put in known good tubes. If that doesn't do it, take it to a tech. Good luck.
