Why do you wish for 12AU, T, or X7s?
They are popular, simple, the goof ball valves are NEVER a good choice for a build, just a cheap way. 50 cent valves in surplus Russia.. LOL
I know exactly why they used them.. They can!!
They are not the only ones to use TV tubes to build stuff.. 6NS7 very popular NOW, sure wasn't 25 years ago..
WHY, surplus and cost.. they use to be dirt cheap, surplus.. Carys favorite valve..
Regards
