Bought an '71 Airstream mid 2007 -- 25 foot Land Yacht with double beds. Had it in the campground twice last fall, but now am doing some repair work. The PO had not found a leak in the shut off valve feeding the toilet, so I get to replace the toilet's plywood base that sets on the black tank. And, of course, there is plywood where the bathroom floor meets the rear wall that needs attention. The bathroom is stripped, except for the shower pan. I've been waiting for suitable weather to get under the unit for cuting the access hole for the shower drain, hopefully in the next week or so.
As I fully expected, the Univolt does not work. My forum searches for information have come up empty, so I am hoping someone might have a schematic for a Univolt Model 35, S/N 9425. This unit does not have filter capacitors; there is a three transistor circuit that apparently tells the SCR when to fire. The full wave rectifier has had a mechanical failure, and I can't determine a replacement without the schematic. I do intend to replace it with a better power supply, but I just like to fix things if I can.
I appreciate any help (and all encouragement).
