Or should I just use a standard coaxial cable?
Use the shielded twisted pair.
The cores carry the Signal Flow and Return.
The Shield gets connected to the Source Chassis and connected via a small ceramic cap (smd1206) to the Receiver Chassis.

If it was PRP resistors and black connectors it would suit black better. Your call guys, just vote.

What is your subjective opinion, comparing these WW to the Vishay bulk metal you got from Michael ?

Sorry Ricardo I used only Vishay 1280G trimmer but the data sheet of these WW isn't bad 20ppm 5% and the price is fair please let us know how works.

hi all,
finally after +1 year MC gain stage with Azur 540 I've made ptp Salas RIAA, MM version with buffer. Still not in the box and no listening yet, I think the hum is bit high, managed to get it down a bit. measured output with Visual Analyzer. Supply is Salas shunt reg with 5 leds.

Is this quite normal? what is the average noise w/o input signal, got it 23mV rms with DVM. Advice to get hum down is appreciated, looking forward to listen and many thanks to Salas
