Hi Richard,
Here's a copy of the 19-page manual: http://manualzz.com/doc/11597273/model-4630-refrad-reference-radiator-manual It doesn't have schematics but maybe there's something in the manual that may help. Also check this 20 year old e-mail from the EMC-PSTC archive: https://www.mail-archive.com/[email protected]/msg05914.html Maybe this person has some useful information. It's a long shot but still worth a check.

Whilst in storage for the last three years it has developed a fault, I think with the 70 V power supply, but I do not have the schematic to help with further investigation. Can anyone supply me with a schematic of this comb generator, or other circuit-board level technical information that might help? Thanks in anticipation, and a happy Easter to you all.
