I do not want to power up without a schematic to confirm previous attempts at restoration. Any help would be greatly appreciated.

Several tries. This schematic is for a S-55. Perhaps it may be close enough to help.

At least I should be about to avoid the hot spots above 600 volts with my DVM. Barrie Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
