At first, nothing - no HV, no B+, no filament glow, then I realized I forgot to plug the cheater cord in
That's a 5AXP4 test CRT I've installed


With that hooked up, I was treated to a nice CRT glow and loud buzz from the speaker. At this point I still had the HV cage and tube shields off so I shut it down. While replacing those shields, I realized I also had left out one of the 6AU6s in the IF stages


Now, I've tuned it to channel 6 (OTA analog VHF station) and got some good sound, but the horizontal and vertical sync are all over the place I tried a DTV converter box and got no sound and no picture

So I grab an alignment tool and reach around to the horizontal coil and start tweaking it. At one point I get a high pitched squeal, then at last a stable picture


Still no sound at all though. I had a similar issue with my 24A12, but not as bad. I went back to channel 6 OTA and can tune in both a good picture and sound. I'll try my blonder tongue modulator later, but next I'm going to try the 12LP4.
