Update from the Pld64goat:
I Am Going IN!!

It's interesting to get these out, i've done a few. Start at the back: 1. Remove the heat radiator/Low-Voltage Regulator assembly as described previously. Getting one of the mounting screws out is fun, getting it back in again is even more fun..

Also interesting is if you start swapping the PCB on top of the HV between mainframes (7603 i think it were). There are two versions, where the 15V connector from the powersupply has + and - swapped (not the arrow on the pcb, but the traces on the pcb). And one scope had a "straight" cable and the other one a "crossed" cable to match the PCBs. So i had to swap the pcb and the cable from one scope to the other. If you only swap the pcb it won't work. I know from experience.  :scared:

The more I watch Old64goat's videos and study the 7633, the more I want a 7633 or 7623B.  But I already have a 7603, two 7834s, and other 7000 mainframes so it is difficult to justify.

Mr Old64goat is officially in the 'last man standing' tech arena now, about to face unknown adversaries   :popcorn:   :popcorn:   :popcorn:

Let's pray he finds a BBQd resistor or two, some dry solder joints, or an easy to replace leaking capacitor, and end this painlessly   :-+
