Re: Why Both EAA91 and EB91?
I'd never even been aware of the EAA91 until this thread. EB91s have been breeding in my junk box for almost 60 years, however.
THe EAA91 number seems a bit silly when there's long history of suffix letters in valve designations to cover different bulb shapes.
Does the EAA91 do the bright heater flash on turn on in series string heater systems that I associate with the EB91?
