I think that I know the answer to this question, but here goes. With the typical high line voltage here, I noticed that some of my voltages were a little high on my Philco 18. So I did what I occasionally do and installed a 50 watt Dale dropping resistor after the switch. It's a 23 ohm (all I had on hand) and it dropped the incoming voltage a little more than usual and it is something like 104 volts. The "tuning eye" is now not as responsive, but working. Is this because of the lower voltage? What would be a better choice resistance? (Yes, I know a bucking xformer is better.)
