[Boatanchors] 5U4 vs 5Y3

[Glen Zook]

Yes, and no!

You have to watch the filament current.  The 5Y3 draws 2-amperes and the 5U4 draws 3-amperes.  If you have one, a 5R4 would work fine without worrying about the filament current.  The 5R4 also draws 2-amperes.

Can a 5Y3 be subbed for a 5U4 for testing purposes?
