Yes Robert, I was replying to you concerning your LCR phono preamp. The posts got mixed due to poor timing.
I have been buying some old UTC inductors to make an LCR RIAA EQ. I have the proper values of VIC variable inductors and a few HVC, MQx, ML, that MIGHT work but it would be nice to know if I have the right ones before attempting a build. My inductance meter is pretty good, accurate to 1% and able to read inductance and Q at 100Hz, 1Khz, 10Khz, and 100Khz. I also have a bridge if needed, to measure at the exact freqs, 50Hz, 500Hz... etc. I'm just trying to figure out the details. Don't know if their shunt capacitance is ok. Do you sell your EQ networks seperately from the preamp? Some of us diehards prefer tubes over IC's. I've got a nice Melos GK-1 that I might modify with some LCR's, or better - build from scratch.
