L-100 Scan twice, doesn't pick
Hi all,
I have a sick L-100. Scans twice, doesn't pick. Battery test does not work. Tubes seem to be good, I have a new 2050 arriving this week, just in case. The mech does trip if I pull the 12AX7, pull and replace the RCA plug or ground pins 3 or 5 of the 2050 TEU-1 was rebuilt a few years ago, all new caps and resistors. I'm using a free play box. Prior to this happening, if I'm correct (it was a while ago), intermittently, if I made a selection, the keys would not latch sometimes, and sometimes they would. Then it would pick. Then I heard a "pop" and since then, the keys latch, but the box does not pick anymore. thoughts? |

L-100 Scan twice, doesn't pick
Thanks John,
I'e cleaned the detent switch, but that did not help. The troubleshooting manual is pointing towards a bad format, although I find that hard to believe. I do have a replacement format arriving in a few days. -Wayne On Monday, January 23, 2017 at 2:32:27 PM UTC-5, John Robertson wrote: On 2017/01/22 7:55 AM, Wayne B wrote: Hi all, I have a sick L-100.

Hio Wayne,
I agree, Tormats were very reliable. It could be a broken wire on the RCA plug - does it show continuity between the pin and the shell? Should be under ten ohms if I recall correctly - more like 3 or 4 ohms in fact. Look for the "Battery Test" that will help determine if the Tormat and Readout circuits are working correctly. You will have to align the replacement Tormat correctly, this is shown in the manual. I suspect you have another problem than that though.

L-100 Scan twice, doesn't pick
John,
Yes, there is continuity across the RCA plug, also OHMs out fine. The TEU-1 checked out ok on my friend's KD using my tubes as well. The tormat had been opened prior to me getting this box, I don't know why. I opened it and didn't see anything obvious, the resistor reads 183Ω. I have a "new" tormat arriving in a day or two. I'll keep you posted. -Wayne On Sunday, January 29, 2017 at 12:44:01 AM UTC-5, John Robertson wrote: Hio Wayne, I agree, Tormats were very reliable.

L-100 Scan twice, doesn't pick
Did you try the battery test?
Basically you take a 1.5VC battery (AA or C cell) and put it base (negative) against the control center case and you tap the centre pin of the RCA plug against the positive post of the battery a couple of quick times. Plug the RCA back into the Tormat socket on the control centre and make any selection. If it now plays ALL (or most) selections then the Tormat are readout circuit is fine. If it just scans back and forth try the same test, but reverse the battery so the positive termina is against the control centre chassis and tap the Tormat RCA centre pin to the Negative shell of the battery - plug RCA back into Tormat socket on control centre and again make any selection. If you now play (any) selections then great, the Tormat and readout circuits are fine (or either needs attention if only some selections play - ALL will play if Tormat and Readout is good). Hope that is clear. You never said if you tried the battery test after all...don't assume the Tormat is bad until you have done some tests...

John,
Yes, I did the battery test, it failed. I replaced the tormat today, and now the battery test works. I did get the box to pick, I think there were two issues, 1 - the tormat and 2 - the wipers on the numbers relay on the stepper used to have an alligator clip that held them together and were then jumped to the "T" test point. That clip had also fallen off. Now on to it's next problem. It won't pick selections B7, D7, F7 or H7. -Wayne On Sunday, January 29, 2017 at 7:21:52 PM UTC-5, John Robertson wrote: Did you try the battery test?

This problem could be related to the LP selections if that is an option
on your machine. This would either be near the stepper or near the keyboard. See that all jumpers are set to Regular Play or similar. Read the Installation Manual which explains how those are set.

Fixed
Wipers on Numbers stepper needed de-oxit. I cleaned the heck out of them, but it took de-oxit to really do the trick. thanks for the help.
