Hello for all members..I have a ground zero 1.10k and i have power suply broke.Amplifer had a output transistor broken and driver board broken.i change all output transistor/gate resistance/ audio driver/tl494 and driver transistor for suply.The transistor drivers from supply i changed with bd140/bd 139.When loading the power suply(12v) the output raley coupling and the red led light stay ON but very dime.
Imeasured voltage on ic tl494.
1-0
2-4,9

4-4,31

I don t understand why no have output signal from tl494..
