I can't recall any 11 pin tubes. Based on the component count those are probably modules. In the tube computer era they would make an op amp module that had sockets for 2 tubes and another tube style connector for connection of the amp module into the main chassis.

The bottom octal style base with pins is probably for connecting those modules to chassis.

Tube style connectors were used for more than just tubes. Many wire harnesses in consumer equipment used tube bases/sockets as a cheaper alternative to molex connectors. Relays and numerical display devices also used tube sockets/bases at their connectors.

So attached is what I drew..looks like a single amp.
What I reference c1 looks like a resistor may be just open.cap checker did give 1nf. anyway color code on
It white red black brown silver on a brown body..
I assume if values of c1. C2 are correct its a high freq amp.
I agree with the 11pin being just a connector.
I do appreciate the reply.
Most of these modules are 7 pin others 9 pin tube sockets on top all 11 pin on bottom.
