Philco 70 rf-coil
#4

For 1st and 2nd RF yes, the primary number of turns is not that important (though I would try to stick reasonably close to original).
For the IF coil (#19) both windings have to be as close as possible to the original as they are part of tuned circuit.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Thanks for the reply. Unfortunately the radio was removed before bidding was over so I didn't get a chance to bid.dconant — 04:10 PM
