I am considering buying and repairing a Tektronix 2465 but before I buy it I was wondering if anyone recognized the particular failure mode. I ask since some parts are very hard to get and some failure modes are likely hopeless cases.
Channels 3 & 4 appear to work but channels 1 & 2 are saturated to the top of the display (when found using the beam finder). The digital display is also skewed for all readout parameters. (See attached example of channel 3.)
So, does anyone recognize this failure mode? Particularly does this involve an unobtainium hybrid or Tek custom IC? Does it look good or bad for chances of repair?
