THANKS check is in the mail
I removed the buffers and changed R1, R4, C1, C4
Looks the same as without the changes. Just less PCB landscape
7805 current regulator in lower left corner-going to power several panel back light leds (blue) and one EQ indicator led (RED)
may go with larger resistor for 20ma instead of 30ma as pictured 100-150 ohm 2watt resistor?.
Will have total of 9 knobs x 2 leds per = 18-20 leds.
TINA dosn't have a 7805 so the TLE2425 is all I have to simulate.
