Were There Different Runs Of The 40-190?
#11

Thanks Ron! I've done that and I'm disassembling the radio. As i mentioned earlier I've never seen a Philco with this much bad rubber wire. Almost every wire in it is dried and cracked. I should have Chuck's paperwork soon and can make those notations. I guess I was a little frustrated when I said swap the octal to a loctal. You'd think that if Philco made a run of radios with the 6J8 they would have at least released a supplement reflecting that tube and it's associated components. But it's not a perfect world. With the exception of the power supply and 5Y3 socket/tube change this radio appears un-tampered with. My plan is to just put it back together the way it was. Just new components and wiring. Should work great. The audio output transformer is DOA (completely open on the primary side) and I see someone has answered my request for help finding a replacement. Go check that now.

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
