Click suppression varistor for WECO 101a coil + HA1 receiver
« on: April 13, 2017, 01:19:08 PM »
If I'm going to construct a click-suppression "varistor" out of two diodes, will 1N4001 50V silicon rectifiers (e.g., Ebay item number 272401587332) work?   Is the voltage specification critical, or not so much?  Would the 1000V 1N4007 diode work?

My phone is a North Galion that's basically a WECO 302 on the inside.

Any of the 400x series are fine.  The 1N4001 is the one with the lowest voltage rating. The series is 50, 100, 200, 400, 600, 800, 1000 in volt.

If you connect it across the receiver, it really should never experience voltages above 50V, not even a fraction of that, but be your own judge.
