Hi All, I’m having the scan twice no selection issue again with this DS100. Using the troubleshooting chart and the test terminals, it leads me to test K where the test lamp doesn’t lite and tells me it’s a write-in issue. Taking some voltage measurements, a few odd things are, the selenium rectifier in the tormat receiver is supposed to measure -25 vdc, I’m getting -40 vdc. On the test points, points G-H should measure -300vdc. I only get that when a record is playing. When idle, it’s only a few millivolts. I have Mike Zuccaro’s DVD Repairing the tormat selection receiver and when I see him testing that point I don’t hear a record playing so I’m guessing that these voltage test are when the mech is idle. The battery trick works and every selection plays. Does that eliminate the detent switch and anything else? All contacts on the tormat selector and in the pricing unit cleaned and checked including the relay which I know is important. When the mech is scanning, the OA2 tubes flicker like they should. I have checked all the caps and resistors in the receiver. All caps are good including the .05 in the pulse amp. I would really appreciate any help or suggestions. I’ve been trying to figure this out on my own for the last few months and don’t have much hair left to pull out.
Thanks,
Doug
