Steve,
has i said in the first post all the caps i have taken out are leaking. When I started working on the 858 i had a good look all over it, then i put the Avo 8 on the Pos and neg pins of the plug and the reading was ok so the heater chain and the Transformer may be ok then i put power on to the radio by my lamp limitor all looked fine so then out came the Variac with time 240 volts were going in to the 858 but still no sound no smoke no bangs. Had a good prod all over the joints and parts still no sound so then started with the Capacitors takeing one out at a time and testing it and then replaceing it. And has i said i have taken 8 out and not a good cap in the 8. Steve has you can see on the photo C16/C23/C24/C30/C34/C47 are all in one block on top of the Chassis so i will see to this six one by one and see if i can get some sound out of the 858 and then report back.
