Those are the European equivalent of a 6ES8 which is a premium 
remote cutoff dual triode. I think they are the only remote cutoff dual-
triode that was ever made.

There is a mod for the 75A4 to change the first mixer to a Pullen type 
using one of those tubes that is supposed to make a really big 
difference in both sensitivity and overload characteristics.

Written about in ER a while back.
