I'm looking for a 73 K ohm 4 to 5 Watt pot, linear taper. I realize that 73K is an odd figure, & 75K will probably work about as well, but 73K is what is on the schematic. Orginal is a composition type, but I believe a wirewound pot may suffice, too. Let me know if anyone has one or a lead on where best to shop. Thanks & 73, Wayne WB4OGM
