I have it hooked up to a pair of Bozak 302a urbans
and a XiangSheng 728A chinese tube preamp running JJ 12au7 and 12at7 tubes.
I upgraded the VTA's rectifier to a NOS Mullard gz34 and the center position preamp driver board tube to a nos mullard 12au7.
Svetlana el 34 are what im using for power tubes currently.
It seems like each little upgrade is bringing the magic more and more.
Decidedly, i seem to like triode mode a lot, esp for jazz and acoustic music.
The sound is so lifelike and 3d, i feel like 'im there' sometimes.
I like that i get a lot of lush clarity at lower volumes in triode.
I still have a lot of hours left on the el34s, but i sort of have the rolling bug and had read some like the KT-66 in this amp.
What would KT66s bring to the game?
I would also be interested to hear what some of you would recommend as an upgrade to the JJ 12au7/12at7 in my pre amp.
I am very new to the world of tubes, but fairly mechanically inclined in other areas, so i may be asking a ton of newbie questions.
I am so glad i decided to keep this and learned to fix what was ailing my build. I dont think it will ever be easy to go back to SS. lol
