Mallory's own numbering system for Capacitors.
Just wondering whether anyone has any data on the rather odd system Mallory used to employ in the I.D. numbering of their capacitors.
I have established that TP 418 is 0.1mf and TP 415 is 0.05mf both at 600 VDC and that TP425 is 0.02mf at 1000VDC. Unfortunately if there is a code to it, I can't crack it! However, I need to establish what the following represent: RF481 TP438 TP410 A-40980-1. (may be some form of double capacitor) These components are located in a 6volt neg. ground vibrator pack manufactured around 1944. Grateful for any assistance. Trevor |
