time I called Motorola they had
a few things left, but they were
pricey. I've learned to fix broken
width coils rather than replace
them. Rejuvenating the CRT
does wonders. Spend a couple
hours at their location with a re-
juvenator and they will think they
got all new monitors.
On the bench you need 120VAC,
doesn't even have to be isolated
since the monitors have power
transformers. You also need com-
posite video to feed the input. A
pattern generator is best, but the
output of a VCR will also work.
problem I find is that they fouled
up the current foldback adjust-
ment. In any case they are easy
to fix.
I am not familiar with the newer
color systems, nor am I aware of
the level of service required
there, but the old Motorolas pro-
vide me a steady extra income.

The little Zenith 12" guys are very
simple, and mostly they suffer
from broken connections from
people pounding the table.
Simple solder work. Put extra
pins in the edge connector and it
wont fail as often.
There are two power supplies in
each table, they are open frame,
linear types. One puts out + and
- 12 volts, the other is a SV at 6A
supply. I usually only see the SV
units. Half the time, the only

OLDER REPAIRS?
I also wonder if any of you have
an interest in the older jukeboxes
with vacuum tube circuitry.
Home juke repair and rebuilding
can be lucrative, are you avoid-
ing this work because you "can't
work on tubes?" Let us know if
you are interested in this area.
