1. [Amps] contact bounce (score: 1): Author: PACER99@aol.com; Date: Sun, 4 Apr 2010 00:47:23 EDT; Hey guys, I have an amplifier that uses a Jennings RJ6 relay in both the input and output circuits. About once every two years I have to change the output relay. Since both relays switch at the same; /archives//html/Amps/2010-04/msg00066.html (6,809 bytes)

It's good to slow the input relay down on "make" but you need to speed it up on "break" or you will still have the same arcing problem, just; /archives//html/Amps/2010-04/msg00070.html (8,127 bytes)

Reason was exactly what you describe, to slow down the input relay of a PA. It turned out; /archives//html/Amps/2010-04/msg00082.html (9,164 bytes)
