Baby will input switch

Post by cristianoepm »

Hello, I would like to know if it is possible to keep the baby will with 1 input but install a switch so that the input works in parallel (2 triodes) or just in 1 triode. Thank you.

Ofcourse you can. Start drawing. You need to have a dpdt switch. Don’t forget that the unused triode needs an 1M grid load to ground too.

It will be functionally the same as the schematic but with the switching that takes place on the single/parallel jacks moved to a DPDT switch. The two 1M resistors to ground are already present in the schematic. Of course, the single input jack should still ground the input pin when nothing is inserted.
