my head is buzzing/sounding distorted????

Is there still a warranty on the amp? If not, take the amp to a tech for some TLC.

 

If the warrantee is out, try this first. Turn the amp up loud with no bass plugged in, and tap each and every tube lightly. If you hear anything through the speakers when tapping a tube, replace it. Do this because a tube that reacts to tapping by making a sound will do the same if the speakers vibrate it. It's called a microphonic tube, and leads to distortion and feedback. Also check to see if the power tubes all glow with similar brightness. Often a power tube will glow brightly before failing, and can distort easily.

If the above doesn't find a problem, time to go to the tech.

 

...too much coffee

 

I was thinking too much to drink.

 

As was I. Perhaps an icepack on the forehead might be soothing.

 

My head is buzzing/sounding distorted, and also has 60Hz hum, but its my hangover.

 

90% of tube amp problems are caused by tubes. If you have spares, give them a try, if not take it to a tech to test them.

 

One of my amps was displaying this behaviour and has just been repaired. Some components in the phase inverter circuit needed replacement but my amp is 40 years old.
