With tubes, size matters, the bigger the better Seems like el3n is unavoidable, hope i managed to get it before it runs out, like fossil fuels.How's el3n gain compared to standard 6sn7? Same? Lower or higher? , considering it is not running at full power.We are in the same boat. 6sn7, 6as7 infection.I am curious why bigger tubes sounds wider, maybe an expert like @2359Glenn have some opinion? Electrons swimming in wider space perhaps?
