2 of power amp tubes glowing really bright!!!

[TomW]

I've just been playing on my amp for about half an hour and no one was in the house so I decided to turn it up abit louder than usual and all of a sudden the amp started to hum really loud and the volume dropped slightly. So I looked in the back of my amp and 2 of the tubes were glowing really bright. Does this mean the tubes are gone?
If so does anyone know of a good guitar tech in Leeds that doesn't charge a fortune?

i arent sure about your valves but rockshack in burley do maintenance fairly cheaply.

CAUTION!

There could be several things wrong.

The amp isn't properly biased;

The tubes aren't properly matched;

And/or the output transformer has made love.

Don't use the amp and have it checked by an amp tech.

Cheers Ratrod, I'll hopefully be able to take it to an amp tech this weekend. I was thinking there may be something wrong other than the tubes as it wasn't too long ago that I had them replaced, but i'll just have to see. Hopefully it won't be something too expensive.

Could still be the tubes, new ones can be faulty.
