If the 500K you referenced with the mix up between #23 and #24 above was the 500 ohm you mentioned at the end of your post, I doubt that will solve the smoking cap problem but will no doubt cause problems as we get by the major hurtle. As for "measuring voltages" no, not at this point. No power to the set until the magic smoke problem is solved. For that you need to measure resistances. For example from the + wire on the 10mfd to centertap. You don't need to have the cap in for this, in fact, better not to. We are looking for a short on the B+ line.
As Morzh said, there is not much involved at this point. New good caps blow like that generally due to wrong polarity, bad rectifier or miss wire getting a lot of A/C on them. Let us know what you get for resistance on the above test and we will then try something else.
