[Amps] Clipperton L Conversion to GI-7b(t) Tubes

[Tim Long]

Hello All,
I know there have been several conversions and they apparently leave the 
stock tank circuit as-is.  The stock tank circuit could stand to be 
re-designed anyway.  I can't find any "typical operation" data for these 
tubes (lots of mechanical, maximum, and pulse data).  I would like to 
know the effective load resistance.  I would like to know the input 
impedance.  Thanks in advance for any help.
