It would be very helpful to know what tubes they might be such as 6L6, 5Z3, 80, VT25, ETC. I see a lot of octal
bases that they started to use in the later 30s. Four pin tubes were earlier than that back in the 20s. Tubes with a top connection were either a plate cap or grid cap depending on the tube application.

The tube with the brown base is definitely a rectifier tube, probably 5Z3 or an 80 tube. It could also be a 5Y3 if it has an octal base. The VU Brites are a little transformer device used to increase the filament voltage on somewhat failing picture tubes. Also I saw several Compactron tubes which were generally used in television sets from the 60s to 80s approximately.

Think I should try to barter with my 8-track tapes?

Showing an RCA box means nothing- show us the numbers on the end of the box at least!
