/\  no.  the Collins 30S-1 is AB1 cathode driven.  

I'd forgotten that one. Not sure you can really call it grounded grid, though,
since the grid is grounded through 220pF so that feedback can be applied.


For some reason, the term 'grounded grid' always for me conjures up visions of
6AK5-6J4 Wallman cascode circuits in 2 metre converters back in the days before
Nuvistors.....there's age for you!
