Great looking corner set, "fixmeplease," and you're right, it looks very nice in that corner! Basically, it is a very good idea to replace the Selenium rectifiers. Do use new silicon diodes, do not use new old stock selenium rectifiers. You may or may not need a series resistance, sometimes the DC voltage output is close enough to the schematic value, to be ok. the Sams should list the voltage after rectified by the diodes, and that will be at proper line voltage, usually 117vac. The resistor above the seleniums, is a fusible resistor, and they often don't look great, even when they are OK. Yes, you can add a connector in line of the Yoke wires, I have done this more than once, for ease of service. I recommend using a mating M&F Molex or AMP Connector bodies, that have enough "pins" in them to allow you to add a little separation of one space, between the two or three heaviest Yoke wires, just my own opinion. Best wishes on your continued restoration of this classic, and uncommon set.
