when the oldie is complete, there must be a little roll of that silver solder inside !
All tube Tek have this white little roll mounted inside anywhere, different places by Type.

About CA.

Tek 545 is a early model. Later models are 545A.
There was also some differents in the plugins, and scope mobiles also.
The old classic scope mobile what is the "original" for a 545 without A, is the Type 500/53.
The old classic scope mobile what is the "original" for a 545A, is the Type 202 (with tool box and plugins housing for 2 pcs.)

The very old style 2 channels plugin what was typical used in the Tek545 is not the CA, it is the Type "53/54C"
This plugin is very closed to CA, and of coarse the CA will work also perfect in the 545. Bot plugins, the CA and 53/54C run 15 tubes.
There was also some other plugins where the Type name starts with 53/54 , they are all useful for the 545.

greetings
