Thanks for that info. My VFO feels fine when tuned, but looks like there may be contact problems when the VC is close to either end of the range. Wonder what lube you used on it?

Back to the Rectifier Brd, part X43-1370-02 for the 530, coming off the 800V line is a line designated as 'HV' with R5,6&7 in direct series, each one being a 680k resistor. I haven't managed to find those in the parts list

. I wonder if they too are composite resistors which may warrant attention?
