Hi there,
This might be a bit offtopic since I'm bringing
Telequipment scopes to
discussion. But then again Telequipment was bought by
Tektronix in the late
60's I think, so I hope all is well :-)
As I said I own two Telequipment scopes (bought them
for 30 pounds), models
D43 and DM53A with the following problems:
a)D43: Although I have both beams on the crt and the
timebase seems to be
working ok, I have neither focus nor any signal at all
(ie just two thick
straight beams);
b)Lots of trigger misfires. The signal "wanders"
across the crt window. Trigger level looks ok though.
Timebase looks ok;
Can you guys advise me on what to do or where to
start? Both crt's look ok
(no burnt spots, etc) - I'm sure we're talking about
minor stuff here.
Both scopes seem to be built like a tank - the quality
of wiring is superb -
and there's life in them - it would be a shame to
scrap them just like that.
Thanks in advance for all your
comments/suggestions/tips
Best Regards
