The subject says it, but it isn't fully ot: The C1-122 is a Tektronix
7603 lookalike, the 1st. was the C1-91, the C1-122 ist the 2nd. edition,
Plugins have the same connector Pinout but with metric pin distances and
the Plugins are a mechanically a little greater.
It should be possible to get a Tek 7000 Plugin to work in those scopes
whit an mechanical adapter, but not vice versa...
The electronics are totally different...
I've got this scope from ebay for only 1,99 Euros, with the hint, that
there is something wrong in the HV supply. I've found, that both fuses
on the primary side of the main PSU are blown, so I've searched first in
the PSU for problems (that is a mechanical hell, had to remove around
40 screws to get to the switching transistors....).
Unfortunately the HV plate was fallen out of the assembly, disconnecting a
few of the connectors and I don't know where tho plug them now (only 3
connectors, 5 wires), so I need a shematic from the PSU to reconnect them
properly.
Can someone here help me please?
Kind Regards,
Holm
PS:
ebay number is 190068339560 for those who are interested in a picture of
the C1-122...
