Hi all,
Put this together and although a signal passess through there is no delay.
1) All ICs have the approx -15v on pin 4 but there are some low voltages on some of the pins (see pics)
2) TP1 has signal
3) Level control works
4) Blend control 'works' in that you can hear a difference in the level of the output but no other control impacts the signal
6) TP2 there is signal but not delayed and BIAS1 trimmer takes away some of the static noise
7) TP3 there is signal but GAIN1 trimmer doesn't really do anything
I am not really sure of the next steps as the signal does seem to hit everything, I am assuming its not MN3005 as I got them from a reputable dealer but could be.
Any ideas as to where to start?
