ok , i have now got the funds to build my pico se, so i am going to start with the meter pcb .

I have a couple of ? what valve can i replace R3{1k69} with and can i replace the lite on 1000e bargraph with leds or will this reduce the resolution of the meter circuit.

Testing the pcb. can i inject a signal for a ac signal gen.
