I am looking for info regarding the coil data for the old white's PI 1000,2000,or 3000.
Pls let me know if you can.I got all the components schematics but no coil data.

My old notes show that the coil was about 200uH at 1.30 ohms with the cable attached.
For the 10" coil it was 18 or 19 turns of #22 stranded pvc hookup wire. R16, 5.6 ohm is very important and should be a 1 watt metal film. This part on the original detectors cause instability and drift as it aged and absorbed moisture.
Good Luck
