We uncovered several cases of Western Electric twist lock cans made in 1945. Your first thought may be UGH! dried out and worthless. Not so! True to Western Electric quality standards, these caps all reform to levels way beyond that which we find acceptable today. As a matter of fact, once reformed, their leakage is 1/4 that of today's capacitor of the same value and voltage. ESR is also similarly lower. New, old stock. 1-3/8" diameter x 3" high. All leakage checked and each capacitor guaranteed good!
