Hey guys. I'm in a new situation. My power tubes have gone in my Laney AOR. It's using EL34's in there. This has never happened to me before, so can I buy some EL34's and replace the old ones or do I have to do more than that?

Was looking at JJ's. But they seem to be rather expensive. Can anyone name any decent cheaper alternatives?

Thanks :-)

Which tube was in there before?
If you look for that exact tube you should be fine.
Tubes are about as easy to replace as a lightbulb.

Ps. If you really want a different tube, look at Tube Amp Doctor.

Groove tubes were in there before, so if I buy some of the same tubes I can just change one or do I have to change all of them?

Power tubes need to be replaced all at once, preamp tubes you should be fine if you do them one at a time.

The larger tubes are usually the power tubes.

Lots of videos on how to replace tubes.

The long and short.

1. Buy matched power tubes - make sure its the same power tubes as the ones you have in your amp
2. Pull them out of socket (use minute left and right nudges if its hard to remove)
3. Check the position of the key in the centre of the tube (where all the tube pins are)
4. Take new tubes, rotate said tube key such that it is in the same position as on the old tubes.
5. Slot tubes in
6. You're ready to go

You might want to have a tech bias your amp, but you can actually ignore this step without any technical trouble.

What the kitty said. AOR's have a bias adjustor trimpot in them. You should get somebody check it but you should be ok. However, they may be biased on the hot side and may be partially responsible for the others failing (a hot bias will wear them out quicker). Worst case is that they redplate and fail.

It's inside the chassis. It's used to adjust the bias of the power tubes. If you need to ask what that is you probably shouldn't be poking around inside there yourself.

Bring the amp to a tech before you kill yourself. Guns don't kill people, fiddling inside an amp kills people.

I'm pretty sure Grove Tubes are a lot more expensive than JJ's, I always thought JJ's were pretty cheap.

I think JJs are among the cheapest around. Not sure about the Chinese tubes like Ruby or Shuguangs tho.
