One option to service this set is to remove both the CRT and chassis from the cabinet then connect the 2 on the bench. If you have a long length of spare HV wire for the HV lead you could extend the HV and yoke leads to reach into the cabinet with the chassis outside the cabinet and use the sets own cabinet and CRT as a test jig for it.... probably good to put any floating HV connections in a glass jar or mug to prevent arcing.

Couldn’t you just back the crt into the chassis, with anode and yoke connected, when both are outside the cabinet? Just park the crt where it was minus the cabinet, or am I missing something?
