Hi there.
I am in search for some 814 triode curves.I found two on P.Millet site(thanks Pete)yet,they are quite different.

I want to replace the 807 triode connected tube,used as a driver,with a more linear tube.
Looks like the 814 is the one.

Can anyone help me locate some curves?
Thanks

SD
 
I found four 814A tubes in Original box from 1944 at A Ham radio sale today:D
Not easy to find..:rolleyes:
