Re: first coil
to: G Wilson
1) conductive plate is fine.
2) You might try some gentle 150 to 200 degree (F.) heat in a kitchen over
with the door slightly ajar. Approx 45 min should dry out all the solvents.
3) With the reistive network chokes are no longer necessary.
4) Cross linking is a good idea.
