Hi Bert,
Thanks for supplying your experience. Yes, I may be going overboard, but the long repair stories on the EEV Blog bring out the preventative engineer in me!
The RIFAs capacitors in my input filter already have cracks (are will be replaced), and an open-circuit focus chain resistor was the original fault when I got the scope.
When I replace these resistors I replace the high value ones with two resistors of half the value in series to split the voltage drop.
They seem to last longer that way.
Thanks again,
Alastair
