I have most of the parts in my bin but they are SMT. I have the through hole caps, diodes and resistors but not the opamp. I guess I will toss the stuff I need in the cart and order it along with the transducer. Not sure if I need the board yet. I may just do it on the breadboard first. I will order mult-turn cermets for the trimmers and metalized poly MKTs for the two RC caps. Looks like the brdige cap should be aluminum electro to smooth the ripple and the 1n4148 diodes can be just about anything. I wonder of a precision bridge would help?
I have ordered TDS probes from HM digital so don't need the BNC either.
Let me know how things progress.
