@ Erickminer- was going to change the 12au7 on my spirit with NOS RCA blackplates- but was told that my tubes from ayon were NOS RCA as well. can you advise.
Iam also changeing My primaluna pre and power tubes as well,
i am a little confused about the tubes on the power amp. Is it more important to change the stock tubes on the pre amp or the power amp for better sound. the pre has 2 rectifier 2 rgu? and 4 12au7 . THe power has 4 kt 88 which are new from goldlion reissues. 2 12au7 and 2 12 ax7 each.
thanks
tubes are FUN !!!!
