What is happening. This Unit went dead after self distruct (cleaning) nothing works, all fuses are good.

FYI The Voltage on the secondary is approx. 25-30v AC!

I know that the low voltage transformer is bad, I have an open secondary but I only have 80v to primary so even with a good Xfmr my LV output is going to probably pretty low too.
