The original tubes, usually NEC's or Toshibas were banded around the 
bottom with a green stripe.  These are the ones that you want to look 
for, they were more robustly made and will last a lot longer than 
GE's.  Raytheon also branded some Japanese green stripe tubes with 
their name, so, you may look at those.  There were some Radio Shack 
lifetime tubes that I have looked at in 6JS6B size that internally 
looked as robust as the green stripes and heavier than the GE's.

If you do replace with the GE's or what ever else is available, there 
is a mod from Yaesu that adds capacitance to the neutralizing circuit 
to handle the American tubes...I do recommend this mod as it's 
sometimes impossible to neutralize the American tubes without it.
