Trademark 60 Amp - Loses volume after a few min.

Testo:

My "Tech 21" Trademark 60 will lose volume after playing it for a few minutes.   Then the volume will come back after a few minutes and then fade out again.  This is an analog, no tubes, amp.   Could this be a transformer issue?  If not, what could it be.

is there a repair guide for these units?
