Well guys I have some serious issues going on here.
I know at one stage I left the mono block on for about 10 minutes before realising I had no load attached.
I think the mains transformer is knackered or on it's way out.
Mains transformer
no power on 240v pin.
HT 5v?
5V reading 375v
6.3v no reading
Choke
373v
capacitor/resistor side 22v
Smoothing caps positive both read 374v
Output transformer
Z&X 376v
Y 374v
GZ34
Pin 1 375v
pin 4 5v
KT66 both valves
pin 2 5.2mV
pin 4 363v
pin 6 363v
EF86 both valves
pin 1 97v
pin 6 363v
So do you think I have knackered mains transformer?
That explains the bad distortion on volume me thinks way to much voltage. So definitely is not the pre amp.
Any ideas?
Cheers Chris
