I think I could just solder it under the chassis between the two points where the resistor holder above ties into the circuit and then just leave the old fuse style resistor in the holder above the chassis for appearances sake (I cleaned up the glass housing of the old resistor and I looked inside and it looked like there wasn't anything in there anymore which might explain why it measured open).
Does any of these resistors I mentioned stick out as far as one that might work better than the other in this position?
Also I found a couple of capacitors in my capacitor stash that might work in place of the old filter caps in the filter supply circuit, one is a 4.7 MFD 250 WVDC Electrolytic and the other is a 2.2 MFD 100 WVDC Electrolytic.
Would those work fine in the filter cap positions on this radio seeing as they didn't specify a Working Voltage for the original filter caps?
Also the 5,000 Ohm "B" Resistor in this radio's Power Supply/Audio Circuit measures open as well, and I was wondering what kind of wattage of resistor it is, its rather large and looks like it might be a 5 or 10 Watt WW Power Resistor but I'm not sure as it doesn't have any information written on it.
Thanks for your help.
