I was noting the less expensive short plate 60's production @ Blackburn and Heerlen.
I actually prefer them to my older (now super expensive) long plate versions.
A modern 12au7 that interested me (reading between the lines of the reviews) was the JJ ECC802S, but having had problems with the undersized tube pins on their (JJ) 300B/2A3 tubes I never tried them (don't know if it's even a thing with their small signal tubes).
