With the Drake R4C somewhat revived, I moved on to the other items acquired at Dayton. The Swan 250C/Supply: This is in IMMACULATE Shape, and, after spraying the switches/pots with Deoxit, performed perfectly with lots of power output and good reception of received signals. I do hear some HUM in the speaker, though, so I need to replace the Power Supply electrolytics in it. Need to find the Size/value/form factor for those. Shouldn't be too tough a job. But otherwise, the radio is in excellent shape! Hallicrafters SR-150. I tore off the bottom and looked over what was going on. One area seen different than stock was the antenna relay. The contacts had been mashed just enough so that it was sending RF on TX right into the RX as well. Thats no good!!! I tore out the relay and bent the contacts back to proper shape, and then repowered the radio. Now, the Push to talk or Vox works, but I hear no sound from the speaker, and no indication of TX out. Don't know if the Final tubes are toast or what. I need ALOT more work on this, and start measuring voltages to see if the PS's are good. The meter moves abit so that says the AGC works. Maybe the speaker isn't hooked up in the PS150-120. That will take more work. But no meter indication on RX signals so it looks like RX and TX are stone dead. Ran out of time today to work more on it. Meanwhile, other projects are left waiting, like I STILL need to align the Heathkit RX-1 and get it back in the cabinet. Also have to troubleshoot the SO2R relay system I built to find why it doesn't work SO MANY PROJECTS, so little time to do them.!!!! And, to top all this off, I have a Heathkit HW-104 on the way to me that ALSO doesn't work!!! Wish the boss would go on a LONG vacation so I can get some WORK done!! The rule seems to be HAMS only sell BROKE radios at Hamfests! Radios they can't fix. So far, out of 4 radios bought, only one worked and that was after I sprayed the switches. It was intermittent before hand. This would be REALLY Frustrating to a NEW HAM who hoped he could just go home and plug it in and get on the air.
