Thank you Ed,
I ordered 2 sheets of 0.030" poly today and I should have an
0.090" cap this weekend. I also ordered 10 of the 2" torroid cores mentioned
earlier. I'm heating up my 1800pf doorknob with the small RFI choke I'm
using now, I notice about a 1' difference in the air discharge length with
and without the doorknob in circuit: my RFI choke is to low a value.
I'm waiting to see if uncle sam gets my money or if Condenser Products gets
it. I haven't done my taxes yet:(
My coil is now about 1' off the floor, but that only leaves 2.5' between the
top of the torroid and the bottom of the garage door(when open). I've stoped
mumbling, MORE POWER, around the house now and instead I wisper, more room:)
