![]() This is a question for a SX-28A expert out there. Well, I've really done it now. Elmer has struck. I had a wax cap heating up in the RF Deck and so I went in and replaced the bad caps and resistors in the 1st, 2nd, and mixer boxes. Not fun. I really didn't want to, but I didn't think it was going to last long. I marked all the wires as I dis-assembled thinking it would be easy to re-assemble. When I got to the point to hook up the wires connecting to the 4 pins on the top of each metal box I found the wire marker fell off a blackish wire. It looks like it should connect to the mixer box pins, but I don't know which one. It doesn't seem long enough to reach much of the other boxes but I suppose it's possible to get to the 2nd stage maybe. The "mystery wire" is blackish color, and I think it goes to a terminal strip connector. A 1K resistor goes from that terminal strip connector to the 6L7 pin 4. I think it should connect to 1 of the 4 pins on top of the metal mixer box but I can't figure out which one. Does anyone have a diagram of the wire connections to these boxes? As SX-28A is on side with IF cans on top, from bottom of chassis the view looks like this: (Oscillator box not shown) ==Front Rear ==== 1 2 3 4 5 6 7 8 9 10 11 12 | | | | | | | | | | | | |--------------------| |----------------| |------------| | Mixer Box | | 2nd | | 1st | | | | | | | | | | | | | | | | | | | | | | | | |
