Looking for Amperex 8509 VHF Power tube data sheet

[Brian AF4K]

Hey Bob - That's a tough one... 

Sorry I can't help...

For MOST tubes, it's 
pretty easy to run down data sheets on the internet.
For most tubes OTHER than the 8509, you can download 
and install TDSL = 
"Tube Data Sheet Locator" from Duncan Amps.
