old capacitor symbols...
 
2 Attachment(s)
I am restoring an old Fisher 500, one of the power electrolytic is a 40/500V + 40/500V with these symbols on it (please see attachment). My guess is that the two center terminals with the triangle and half moon are the positive connections for the dual capacities and the outer terminals are for the negative – I was wondering if that was the case. I tried an old Google search for “old electrolytic capacitor symbols” to no avail.

Uh, the shapes (and sometimes non-marked) identify pins. The case is common grounded. The pins going *to* the case are merely convienient connection points. Note that these are punched so that wings hold them in slots when twisted to hold in place, hence the term TWIST-LOCK.
