Doesn't that contradict what was said?
If the star ground point was the neg pin of the 100uf cap then
why should I remove the 1K from that point.
I understand that that point (100uf pin 1) is a high(er) current ground point but the board is small...
Moving the 1K to a point down the line near the tone section is closer to the end
of the circuit...won't that be a "dirtier" ground point...not sure that it maters much at
Thanks for the Tips STM.
I'll try them out tonight.
Ok, tried everything above. still get the background noise, no change
The board has a single ground point that connects to the battery and in/out jacks.
Lowered the series power resistor, ceramic .1 across the (new) 100uf cap.
1k moved to the other side of the ground trace.
