If the replacement is physically the same size or bigger than the original then I'd be looking for a short or near sort on that B+ line.

One thing I noticed in the schematics, on the selenium, the anode appears to be on the left and cathode on the right. I thought anode is usually associated with the + symbol and cathode with the - symbol. Both the RCA schematics and SAMS seems to have anode as - and cathode as +. Bit confusing.

I got it now!!!! Thanks for the advice everyone. Voltages are within a few volts on all measurements. Turns out there were two issues. Diode installed backwards and then original 47 ohm resistor was open. Once I got that figured out and bumped the resistor up to a 100 ohm/5 watter (to be safe), all is running great and within specs.
YouTube video for your enjoyment. Thx! https://youtu.be/fScvt2-tFpg

Actually, the arrow is the anode, and, the straight line is the cathode on the silicons, at least.. You did very well, and, sounds as if you did a top notch job.
