Philco 40-185 - Help Needed
#6

Hi Doc,
Glad you figured the connections out. I have done about 3 of the 40-185 radios. But as with any resto job you do, it pays to make several photos of the chassis wiring before you start. I still do, and has saved me many times.

 I know we all have our methods of recapping, and of course the paper caps need to be replaced along with the electrolytics.  i personally do all the basic tests first, field coil, transformer with tubes pulled, visual inspection, tube tests. Then I replace the filter caps first, as they are most critical. Then I do a very brief 35-45 second powerup, having the radio pre tuned to a local station. As soon as I hear a station I will power down.  If no stations, but no hum then I will continue to replace a couple paper caps at a time, test again.   The reason is that if you have a working set, and suddenly after a couple caps it is dead, you know right where to look for the trouble. If you replace 15-25 caps all at once and it's dead, you have a harder time to figure out where you may have made a mistake.
Good luck to you and your new hobby!! Gary.
