Hi.

I recently built 3 Yusynth ADSR circuits onto one board. Ambitious and optimistic as this was one of my first homebrew boards. When I connect up the power, all 6 10R resistors next to the power connection catch fire. I've checked the board and can't find a reason for this. Does anyone have any idea why this might be happening?

Thank you,
Ed

You certainly have a short-cut on the power-rails and the 10R resistor played their part : protecting the circuit in case of short cut.

Time for me to admit my schoolboy error!
I had the TL074 chips the wrong way around Embarassed
But I now have some working ADSRs. Thanks Yves.
