Reneamed: Winter Electronic restorations
#22

I decided I wanted the "Commander of the Air" cathedral I got from Joe to be playing for Christmas so I dove in yesterday afternoon.... The chassis was so easy looking and the radio was functioning before it was restored. only about 8 caps and 3 single Ecaps. 
  The main issue was all the caps I had to parallel and the resistors I had to put in series. The values were weird in this radio. 2 caps were 1600V, all the Ecaps were 450V and all of the resistors were 5K 50K 500K and all I had were much lower or too high so I tied 2 together for each bad resistor. More than half of them were very high.

  I finished the radio and tester her out. no sound and sizzle and smoke.. I put an eCap in backwards... Oops.. Then I fixed that and then No smoke but no sound.... Trouble shot it and found that if I jumped the pair of resistors off pin 3 of the 227 tube, it came to life... Time to call in help.... I called "someone" and found out I had replaced a 5K resistor with a 50K..  Icon_crazy The darn mice chewed off the dot so I mistakenly read the meter wrong....
  Cool right? NO, The volume control/on off pot was crackling horribly... I had to take that apart and put it back together backwards...... 5 times!  Icon_lolno I finally got that right and no more scratching.. Unfortunately there was no volume unless it was turned all the way up. After troubleshooting with "someone", it was discovered that the center terminal was bare. never even used so I jumped it to the first terminal and now it works nice...

  I only cleaned the cabinet and she looks fantastic...!
