Steven,

Pretty cool power supplies, thanks for posting the .pdf file.

One question though, what is the pentode labeled V1 on the third
schematic on the fourth page. It is marked "6AM" 6AM5? 6AM6?

TIA,

steve

The best high current PS I have seen uses the same topology as the GE
1-compactron one but uses several 6080 (6AS7) in parallel.

6080s are good for this. I used to have a regulated supply from an old
Ampex VR-1000 (2" reel-to-reel VTR) that delivered 250V at 6.5A.

I have an
old transformer I am saving for that kind of thing that puts out
650Vct at 850mA. I have a TV transformer that is 550 at 250mA, but it is
being saved also. That's alot of iron.

At the end of the day, the transformer is goung to be the biggest (and
certainly the heaviest and most expensive) single component.

Quality does not come cheap.

It is base diagram 6AM, which means any number of big horizontal output
tubes like 6BQ6, 6CU6, etc.

I was looking at the schematic for a Fluke 407. They did a smart thing. When
they paralleled tubes for more power, they series the filament, so that if
one burned out, the output went off rather than burning up the next tube.
