Yes, I have them (NOS military Mullards) in my KT88 - perfectly fine. (I
believe one of the reasons they were originally selected by AG is that

the sales blurb at the time...??)


I suspect you are right about the causes of EF86 price rise - which in
a

Note you will need dinky little B7G sockets for them...
