If so, yeah, it works fine. It was introduced in here a few years ago by member walterw. Some folk started installing it and liked it. I eventually breadboarded it to test the 3pdt series/parallel circuit I came up with, just to see if the switch logic worked out. Everything worked fine. Wasn't interested in the series/parallel thing so I never installed it. Disassembled the breadboard a few hours later.
Will the program you use recognize 'attenuator' as a separate component instead of 'pot'?
If that's not the shunted schematic you're referring to, then I just wasted valuable internet space LOL.
