Anyone have a tubes chart for a Bell & Howell 202? I thought it would be in the projector casing.

Thanks, Martin but, I am not versed in reading schematics. I need a literal view showing where the tubes are positioned on the amp.

Here is a photo showing the tube sockets for the two missing tubes. Can you figure out the names of these two tubes from the schematic?:

As far as I can see, there are no tubes missing! The schematic shows 9 tubes
and your picture shows 9 tubes in-situ. The other two sockets are for connecting plugs.
Count the tubes and tell me if I am wrong.
