Schematics
 

Thought I was going crazy yesterday trying to trace all the connections around the Horz. output tube. Turns out the schematic I was using from the crosley_9-407_407m-1_407m-2 service guide was not how my set is wired. The schematic from the RCA630TSService manual (which was attached to this thread) does accurately depict my set although a few of the components are slightly different (27K &18K resistors for example. Mine are 27K & 22K like the Crosley schematic). So tomorrow I’ll start checking scope traces and voltages using the RCA schematic. Hopefully something will turn up.
