This is a stock unit.
Just a later supplier.

Be sure to check for leakage from terminal to terminal-
not just to the case ground.
They're bad about that.

Leakage fools many cap checkers into showing higher than rated
values.  Also, +100% to -25% of rated value of electrolytics
was considered "normal" in the 1940s.

Is that steady after leaving it on for a few minutes?
