tried to put together some 6AS7G equivalents with notes (from my personal experience). of course, the usual brand/re-label disclaimers apply. So no need which one is better. The goal here is just to list the main equivalents that may work in your amp's circuit. Did I miss any equivalents?
6080 - low gain @ 2- great vocals, wide soundstaging
7236 - medium gain - great bass, fast and dynamic. Almost SS sounding
5998A - medium gain in straight bottle. Plate construction like 6AS7.
5998 - medium gain at 5, full-bodied sound, same current load as 6AS7
421A - same as 5998 but with matched plates/sections
6AS7G - low gain, the standard tube for most, plentiful
6AS7GA - low gain, like the standard 6AS7G in striaght bottle
6520 - premium 6SA7G, sometimes with 5998 plates
6H13 - russian 6AS7G equivalent. nothing magical with these
ECC230 - european 6AS7G equivalent. haven't seen one in person
6528 - equiv to 5998 but very high gain at 9, twice the current load. Make sure you amp can handle it
6336 - like 6528 but low gain at 2, still twice current load. Make sure you amp can handle it
