What could Account for This? RCA 9TC-240 Power Issue

Sure is except one partially rubbed off U mistaken for a V. Sound getting through the if but the video and sound are misaligned. Par for the course for me. Now that the bottom of the chassis is sorted, I need to get the bench cleaned up and reorganized and put the focus coil back on and the 10BP4 back in. A reset in my head is needed before I go on the next adventure with this!

Numbering aside, I mean that one is a pentode and the other a duplex-diode, high-mu triode, they look very different from each other, after you have seen many of both, they are easy to tell apart, as they are distinctive.

Yes I looked them up and saw the difference. That's why I was confident the issue would be resolved by making the substitution. I'm still not happy with the power situation. The TV is still only pulling about 1 1/2 amps when fully functioning. That's why I want to get the 10BP4 installed and see where I am with the picture as it needs to be. I've checked the voltages in and around the bleeder circuit and all of them are close to what they should be. Still I feel like I'm missing something. I need to check the HV again now that everything is sorted correctly on the underside.
