Title: Dual Relay
Post by: warioblast on April 01, 2020, 12:52:37 pm: Hey guys,
How can I mod this Tube-Town dual relay switcher https://www.tube-town.net/ttstore/kit-double-relais-switcher-6-v.html (https://www.tube-town.net/ttstore/kit-double-relais-switcher-6-v.html)to work with a mono pedal footswitch.
It looks like one of the pin of the stereo cliff jack is connected to ground. My idea is to link the pole below (cf my awesome ms
paint drawing.)
:dontknow: :w2:

Connect these 2 points circled in blue if so.

Thank you. :occasion14:
Yes that's what I want. I'd like to use an old marshall 1 button (mono) footswitch that I have.
This switcher kit is already built. I'd like to use the stereo jack that is already in place.

As for now, with no mods, if I use my 1 button (mono) Marshall footswitch, it only switches Relay 2. Relay 1 stays on all the time.
I think I need to cut some traces

And from the - pin of the relay 1, going to one of the tip pin. It should be 50-50, right !?
