Not yet would like a bit of advice on where to start,

make sure when you start testing, either desolder one end of the resistor diode or take them out of the circuit, with capacitors and transistor it would be better to take them out good luck

Has anyone had problems with these boards,i thought about changing the 'start up caps' c801 c892' one cap is 100uf 25v and the other is either a 3,3uf 50v 0r 33uf 50v,small writing on the cap ? can some one confirm which is right.

Check dry sold joints frist, Resold blast board H.V transformer and connectors come from power supply..
