[Boatanchors] 5U4 vs 5Y3

[WA5CAB--- via Boatanchors]

Maybe but not likely.  The 5U4 has a higher PIV rating and a little more 
than double the DC load current (continuous load current) rating of the 5Y3.  
If the set is a receiver, probably the PIV rating wouldn't be exceeded but 
the current rating probably would be.  If the 5Y3 was a safe substitute, the 
designer would have probably used it to begin with.
