Hsu,
Well I based my point of view on what a friend told me
a few years ago. He did try a 4X500 in GG but could not
get enough ideling current (too low ZSAC).
However maybe it is all wrong. I just checked a data
sheet, you can look here
http://wps.com/archives/tube-datasheets/Datasheets/Amperex-CC-363/4.JPG
Frankly a 4X500 is very similar to 4-250 and 4-400
and they work just fine in GG, if you have enough
plate voltage on them.
As far as I can tell reading the data it looks like
it would work however the plate voltage might be a bit on
the low side.
I would say, for 2 tubes you want atleast 100mA in ideling
current (ZSAC), more would be better but my guess is that
100-120mA would be pritty much on the safe side.
Please tell me how it works if you try. You see I have quite
many brand new 4X500 tubes myself so it´s interesting.
If I was wrong I´m sorry if I did misslead you.
