Hi,
I'm using a DPDT toggle for " Comp. In / Out " instead of a rotary switch, its just what I happen to have,
quote from SSLtech : On the component overlay (second page) two wires going to the "bypass switch" are marked "Defeat makeup when out". One connects to Pole 'A', and the second connects to contact A2.
Firstly, REVERSE these two wires. -If you (as I've done) noticed that it's just a simple "make" connection and possibly just connected them in no particular order, you need to make sure that the wire at the board end which is physocally CLOSEST to the 750K resistorneeds to be connected to the POLE (common contact) of the switch, and the other wire to the second contact.
Now, finally solder a wire to GROUND from the other contact "A1". -There's already a handy ground available at contact 1 of pole 'C' if you need it... ("C1" on the rotary switch as shown).
... so I would connect the " Com " to the Com. or middle contact on the switch, then the " On " to one of the other contacts, and the " Off " to the other. Is this correct ?, and do I still need to connect a " Ground wire " to the " Off" contact ?
EDIT : - I just had a DUhhhh moment - : - so do I just solder a bridge for the " Defeat Gain " or do I need to connect the " A pole and A1 " to the DPDT switch ?
Thanks, sorry for the Newb stuf.. ;D
Thanks,
Chip
