[Hallicrafters] SX-28 Rectifier opinions

[Waldo Magnuson]

In tracing wires and replacing capacitors, I find the previous owner of 
my SX-28 switched the rectifier tube from a 5Z3 to a 5U4GB (because he 
had one I guess).  The RCA tube manual states the 5Z3 has a max plate 
current of 0.675 A and the 5U4 1 A.  Only two wires change so it is a 
simple change but I thought I would get any thought on the subject from 
others who have gone before me.  Thanks.
