Default FS: Antique tube power supply HP 711A

All original HP711A. Last time I used it over 20 yrs ago worked fine. $100 plus ship.

I was going to recap it and replace the selenium rectifiers with SS diodes but decided someone might want an original unbutchered supply. Has upgraded 6L6GC tubes (schematic shows 6L6GB).

Has brass inventory tag from the Tung-Sol company dated 1958.

Manual with schematics available free here:

Would consider trade for a dual tracking supply around 50-70V. Prefer local (SE Michigan) but will ship at cost.

Bump. Last call before I tear into it and modernize it.
