Hello everyone and thanks for reading the post.

I have a Sunn Model T head (Orange knobs, not white)

It's worked fine for me over the past 4 years but today I turned it on, let it warm up and after a few minutes I took it off of stand by and it shut off on me.

This happened multiple times.

Any idea of what this could be the tubes are glowing the normal color, and I'm not sure what it could be.

Please help.

When you say your amp "shut off", do you mean it actually loses all power or simply doesn't output any sound but stays powered up?

-Blown Fuse
-Bad preamp or power tube (or one that's about to go regardless of visual appearance)

Those are the most basic things that come to mind and hopefully the extent of the issue. Obviously it could be far more complex requiring a knowledgeable tech. Have you ever had the amp serviced or changed tubes since owning it?
