Philco Model 47-1230
#6

Well, I finished the recap on the 47-1230, did the bakelite cap, the electrlytics and all the paper/wax ones. Put the chassis back in the cabinet to test, hoping for the best, but not much luck. No smoke, so I guess that's good Icon_biggrin ! But not much else. FM band gets one station all the way across the dial, only a couple of stations on BC and SW bands, this is with the internal cabinet antenna hooked up. I ran it for about 5 minutes and noticed the 6V6 tubes were VERY hot, even the bases, so I shut it off. I have the service manual from Chuck, thanks, and am going to pull the chassis out and start the troublshooting routine and checking test point voltages. I suspect the voltages are too high. Couple of questions before I start: Do I pull the tubes out for the testing of the chassis? Can resistors be tested while in the circuit or do I need to remove one end? Will it harm anything if I power on the chassis without the speaker attached? It looked like part of the circuitry runs through a choke or transformer which is part of the speaker. When resistors age or go bad does the resistance go higher or lower, or do they just open? Hope I haven't gone in over my head on this one, only my second recap job. My first one was a Telefunken table top console, Opus 7084W, and everything went guite well on that. I just bought an extra 47-1230 chassis on ebay so I'll have something to compare to and get the few parts off that I need.

I just answered one of my questions: The first line in the troublshooting section of the service manual says "CAUTION Do not power on the set without the speaker connected....." Icon_redface

Those are details better left to the ones who know. Maybe you disconnected the wrong end of the wire.RodB — 06:22 PM
