So I have two capacitors in the TV that are outside of the tolerance rating of the original capacitors so I'm afraid to power it up until I get those capacitors replaced with the correct value capacitors which I currently don't have any .047 MFD 630 VDC capacitors in my capacitor stash.
I don't want to order anything yet unless I can make a full order and I can't do that until I know this thing is going to be worth my time ordering the rest of the capacitors I need to finish the job and I don't want to put an order in for just two capacitors because that's a waste.
Does anyone have a couple of .047 MFD 630 VDC film capacitors that they could spare?

The test he suggests (pull every tube and power up for a current measurement) will work accurately no matter what capacitance you installed for paper caps...Basically, there will be no tubes to put signal into or take signal out of those caps, there won't even be B+ voltage anywhere...THe only part that should be energized is the power transformer...You could probably glue a pair of leads to a rock, solder that in place of the caps your scared of and not have it do harm or affect the results of the suggested test.
The point here is to verify the expensive/rare power transformer does not have an internal short/current leakage (read that verify the trans ain't ruined). If it don't draw too much current order all the caps when you have the dough, if it draws too much current shelve the set for a few months till you can track down a good transformer or kick it down the road to its next owner.
