Default Scopex 4D10A

Can anyone supply me with a circuit diagram for this beast please? I got it out to use on a copier at work but its gone duff in storage. The Telequipments too big to go on the bike!

cheers,
Rubin

I can let you have a copy of the 4D10 manual/schematics; if I remember correctly, the 'A' version had a wider bandwidth, but I don't know how much the circuitry differs from the basic model. Component quality wasn't great in these: high-value resistors around the timebase are particularly suspect.

Same here, mine blew a fuse. I replaced it and it blew again so I'm guessing it's something else overloading it. It worked fine at first, then it died when my friend plugged something else into the same power strip.

If anyone has a PDF version it would be greatly appreciated. I don't know the difference between version A or B though mine just says 4D 10 on the back.

Scopex 4D10. Y amplifier uses 733 IC for 2mv-10mv/cm, and TTL for the trigger generator.
4D10A uses all discrete, for 10mv-50v/cm.
Both versions are 10Mhz, dual trace. Has not got a good reputation for reliability.
I attach the manual for 4D10A. If you now find you have the 4D10, I'll scan that. Bill
