The power board is what concerns us most right now... you should have around 43VAC coming in from the transformer.. test this across pins 7 and 8 CN1 ( pin 7 feeds fuse F5)...

CN1 pin 7 & 8 50v with no load, fuse F5 49v.


you should then have 39VDC at pin4 CN2

CN2 pin 4 = 67v

5&6 CN3

67v

TP5 and 3&4 CN4...

67v

if you dont have approx 39VDC then the bridge P5 is gone and needs replacing.. also replace R21 ( 680 Ohm 10W) at the same time

looks like a trip to jaycar, but they dont have the 680 ohm resistor

Thanks for the help Gav

also SCR1 2N6564 is missing from the Power Board, what can i use instead of this.
