I am trying to identify the two tubes missing from my '66 RCA CTC-25 chassis.
No tube schematic inside the cabinet.

Looks almost exactly like the same sound PCB used in the CTC-16/XL :O

There's 2 versions of the CTC-25 one with tube sound and a rarer one with SS sound...I had one of the SS sound sets on my bench a while ago.
