Thank you for your replies Guys.

Its a philco 640B Aka philco98 export. See Here.

Ron sent me a copy of philco service bulletins some time ago and No 221 suggests changing resistor 6650 (20K) for part number 33-1177.

I have returned to this set after a while away from it (been busy with work in this recovering economy) and found that the voltages are all over the place, also broadcast band is silent. So in my wanderings around the circuit this popped up.

Regards.

Will.
