Bendix 6003U

I just received a Bendix 6003U in the mail and the cathode ray tube did not quite make it.

I was wondering if anyone might have schematics or repair information on the set. I only have access to Riders Perpetual and not the television volumes.

Also, if anyone knows where I might find a 16RP4 crt.

I am looking forward to messing around with something other than radios.

Thanks in advance.
