Your right about the one and done. Since your add shows 10 resistors for 2 bucks that would allow me up to the maximum 5 each for my 2 sound generators so maybe I'll go that route.
The wiring diagrams are super helpful too Stan, just what I needed.
Theres a number of folks on this forum that offer helpful information that often fall a bit short telling the "whole story" leading one asking more questions.
Not so in your case Stan.
