Rehabing 42-854 AM/SW Portable
#47

Well order from Radiodaze came in today and it contained the mica cap and a few resistors I needed for this job. Dug in and started to replace # 7 and 8. 7 was connected to the band switch so I clipped it off as not to stress the bandswitch terminal and solder in the 100mmfd cap to the switch and to the tube socket. But wait!! 7 doesn't go to the bandswitch but 15 does. I had mistaken it for 7. Replaced it with 790mmfd (had a 800mmfd)
Now I'm on the hunt for 7 but I can't find it. What I did find was a gimmick cap with two wires twisted together. Maybe that's it but I don't think it would equal to 100mmfd.
8 was also awol. How can this be?? Moved 15 out of the way and found 8 (2.2meg resistor). Measured the resistance where it was soldered to and it was open. Then I notice that one end wasn't solder to the socket as it should be. Ahha! That 's where my intermittent was coming from! Remeasured it and was ok solder it in. Soldered in the micas that where disconnected and gave it a try.
Plays fine,Was listening to WBCQ which is around 7.4mc but the SW band has an issue at the low end on the band but I thinking that the oscillator 1LE3 tube is not up to par. No more conking out !!!!!! That was making me crazy!
That this point I'm calling it done till I run across another 1LE3. I'm pretty sure I have some spares but there buried in the shed somewhere. Didn't end up using any of the parts that came in today( was about $75 worth of resistors, micas, and some odds and ends).
