[Jukebox-list] tormat selection

[Wesley Dean]

    Nick, any control center may be removed from the cabinet and plugged in 
with no detrimental effects. Now you an find out if the leakage is herein. 
Removing the main fuse is not conclusive. The other primary leg is still 
connected.  Wes

Thanks to all the ideas concerning the tormat
selection problem earlier this month.

After getting some time to really break it all down, I
have found the issue. It indeed is warm up time. After
setting up several meters to monitor voltages on the
selection receiver.  I found the problem (missing the
first selection) only happens in the first 28-35
seconds that the juke is pluged in. After that,
everything is great.

I assume that it was just me being impatient. Plug it
in a immedatley making a selection (within 10
seconds).

It is possible that one of the new tubes might be a
little gassy but, I think I'm nit-picking this thing
too much. I've got bigger fish to fry.

Now I found, by accident, that the 101 case is
shocking me. I didn't notice it until I was standing
bare footed in the kitchen and punched in a selection.
Sure enough, I tested it and I've got around 90vac on
the cabinet. It's very low amps because you can't
really feel the tingle unless you are touching it
(barefooted) with a sensitive or thin skin area. You
can't feel it with just your hand. None the less, the
voltage is there.

I have unpluged everything like amp, lights, etc. and
I have the problem isolated to either the selection
receiver or mech. I'm suspecting the windings in the
tormat transformer.

I did have a couple of questions that I though you all
might be able to answer.

Is it safe or ok to power up the selection receiver
with the tormat unit unpluged from it? I didn't know
if this would cause any problems or not. According to
the schematics, it appears to be ok to do that but, I
figured someone might have some first hand knowledge.

The other question is, would it be ok to add and earth
ground to the chassis of the 101? I'm guessing that by
adding an earth ground it may take away the tingle of
the 90v.  I'm understand that by adding a ground it
will not solve the underlying problem. I also know
that it could cause the faulty component to burn out
or fail quicker than without the earth ground. I'm
just curious about your oppinions on that.

Thanks,
Nick
