Hi everyone. Before testing the ADR 30 for delayed signal, I would like to check if everything is fine with the dry signal through the board (in to out).
Is it ok to do such a test without th BBD Ics?
This way I avoid risking really expensive Ics like the Lm3005.
Which Ics can I omit for such a test? I just need only the necessary for dry signal.
Thanks in advance.

You only need to fit U4, U12, U16, U11 to test the dry signal.tedsorvino wrote: ↑Tue Nov 01, 2022 7:09 amWhich ICs can I omit for such a test? I just need only the necessary for dry signal.
However, if in any doubt - check the power supply first before plugging it in to the main board.

Thanks Tony. Of course I will do. The PSU will be connected only after making sure it gives +/- 15V dc per line.
I need to check just to make sure there is no problem with shorts, or anything distorted on the dry signal line.
Then if all is good, I can focus on the more exotic parts of the circuit like BBD and LFO.
