Morning All well I have dived headlong into my SX-28 restoration. The first order of business was to try to get the wiring correct in the audio output stage. It had a replacement audio output transformer, and the wiring to the headphone jack was all wrong... end result was that there was NO audio available at the speaker jacks on back and bad audio with headphones.
I had a parts unit here so I took the audio transformer out of it,and put it in the one I'm restoring. I wired the headphone jack up correctly, and the speaker jacks on back. I now have decent audio from the speaker terminals with the factory speaker, and so so audio using a 8ohm headset at the headphone jack. HOWEVER, the 6L6's ( someone subbed out the 6V6's ) run scalding hot.. I mean.. so hot you can smell them. I have changed EVERY component in the audio section around the output tubes, and the 6SC7. Anyone have any solutions to why these tubes are getting so hot? thanks in advance r The "AM" voice of Shreveport, Louisiana USA formerly WN5AIA and WB5AIA I got my Extra Class the old fashioned way...
