Default L-100 Scan twice, doesn't pick

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.

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, 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..

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.
