New Tubes for an Old Zenith Universal

Put an new power cord on my Zenith Royal G503 Tip Top. This is my first foray into it innards. not much there compared to My Trans-Oceanic 600's. It is going to need to be recapped, the Selenium rectifier is functioning fine but it is scary looking and is getting the heave-ho. The Tubes: except for the 1L6 (got lucky there) all need to be replaced, the 3V4 is marginal. The question is which brand. My favorite tube line is the JAN tubes, Joint Army Navy, which where made to government spec's by whomever got the contract. I don't have such a choice with this Zenith Universal.

I need 2 1U4's, 1 1S5, and a 3V4.

What advice do you have for me.
