National SW-3 question

Any ideas how to duplicate that or a simple workaround? Does anyone know the DC resistance of the original unit? I have no idea why such a value was used - any explanation? TIA, Bill IN the early seventies, like 1971 or 72 I'd say, CQ ran an article by Bill Orr about making your own National regen receiver. My first thought was that it was an SW-3, but I can't remember. But if someone can dig that article up easily (it was on the cover), it might provide some insight. Michael I'd like to see that if anyone has it. -Bill |
