I have access to several of the GI7B tubes. I have seen some interest
shown in those tubes here on the reflector, so if you are looking for
one, you can drop me a line. The price is $55.00 ea. plus S&H.
Here is the data on the tube. You can also find more info on this tube

Also a good article about the use of this tube is at:
