DDD mfg co High Voltage power supply?
I'm having trouble locating a schematic for this Power Supply
D D D Mfg. Co.
uses 6BG6 GA power tubes and is in the 19" rack mount configuration.
any help would be appreciated, I seem to be striking out on with the usual web searches. Also the local ham radio flea market was lot's of fun. I risk being down 25 dollars if I cant fix this.

case work like this would be, 'a bit more ' than $25 new.
make a nice amp chassis.
Chances are good that if you replace all the electrolytic and/or wax caps this power supply should work fine. Hopefully it was not modified or "repaired" by a previous owner. Give it the same treatment as an old amp or radio being fired up for the first time in years.
The good news is that the unit came with a set of replacement filter caps, witch I think are oil filled paper. I will be digging into it, but it would be nice to have the schematic. Perhaps I will just draw the schematic as I work on it. There are also some electrolytics I spotted. You know the multi section can type. So with something that old, it might take a multi prong attack. I will know more soon. I think that this was not made in any volume, so that could explain the lack of information. This is intended to replace a Fluke 406 witch is on loan from a goooooood friend, and he deserves to get it back.
