Yep, took a look at that and it sure was the same unit, the Eveready version of the service information was missing quite a bit of helpful information including the parts listing and the information about the transformer and the "filter can" assembly and how to service them, and the rest of the resistors and capacitors and their values.

So as far as the Filter Can assembly goes, since it was meant to be removed and replaced as a whole assembly I'm assuming that in order to replace the old filter capacitors I would need to just cut out the old filter caps and just solder new capacitors onto where the old capacitors that were in the filter can soldered to?

Also I'm going to assume the original Filter Choke is more than likely fine yet so it should be fine to leave that in circuit am I correct?

As for the old filter capacitors go, I'm assuming I should just go with 450V Caps to be on the safe side since they didn't specify a voltage in the service information?

Also I see the 3 Meg Grid Leak Resistor in the parts list, but I don't see the second fuse looking resistor that was on top of the chassis listed in the parts list, unless I'm missing something...

Thanks for your help.

Edit: I figured out what that second fuse style resistor is on the top of the radio chassis, its the 50,000 Ohm (50k Ohm) Plate Resistor which measures open and I searched eBay and couldn't find anything.
I know of someone who might have the part (its an older gentleman who goes by Glasslinger on YouTube, who works on these old 1920s vintage TRF sets all the time) but I'm not sure how to go about contacting him and or if he would even be willing to send me one of his resistors if he had one.
