RE: 2 Comments for Fla Charlie ...........

Thanks for the suggestions Jeff. When I posted earlier asking for suggestions for the negative supply, Ray Moth suggested I use a choke in place of a resistor in the CRC. For the voltages I had given in the post (probably not accurate) he thought a 1k resistor might be in the ballpark.

Whatever the value of the resistor turns out to be (let's assume 1k) are you suggesting that a choke with a 1k DCR should be used in a LCRC configuration? Or an LCLC using chokes with DCR of 500 ohm each? Or do you suggest using a low DCR choke in LCRC even though it must be followed by a higher value resistor to get the voltage into spec?

I'm not sure what I'll end up with but I'd like to hear your ideas on this.

As for the wire suggestions, I may experiment with that later or maybe not go quite as large. As a practical matter, how do you connect that large a guage to a standard size terminal strip or socket pin - especially considering that there are usually other leads from resistors, caps etc attached to the same place?
