We have a winner.

yup! Bubba coulda been me for that matter. Hairline 'lightning' crack in the loading cap from the screwhead to appx 7oclock in the pic.

Back off on the screws, and fs is back up to where it should be.
So diaphragm seems fine as expected and I'll look for a replacement LC.

The light coming through the 2 leads where they dive down to the VC is just those gaps colored by the factory ambergoop,
It is a strong light (no other sources in the room), and a fast lens.

Bright light indeed! Cool, dodged a bullet! Kind of surprised it sealed back up.

The number and variety of repairs I've done or oversaw due to folks over tightening joints where a torque wrench [or calibrated wrist/elbow] is ideally required staggers me when I think back over the decades, especially where soft or brittle materials are involved and/or the right hardware wasn't used.
