Yes - it has base-pins just like a vacuum tube.
The metal cap is on the top of the recifier metal case.
Unit is about 3.5 inch tall.

I would think my two replace a HV tube since it rectified for 2 x 813's.

I did contact Semtech, the reply said nothing of help.

Have not had the chance to check any wiring and have no schematic.
