I'm about to get a kit for an EHHA rev.A and started thinking about the tubes.
I started my DIY-Career with a SOHA, later on I added the jisbos buffers.
I did some tube-rolling and liked the GE 6680 best. (Not depending on the phones)
(I also built a SOHA II, a Mini³, a M³ and another Jisbos-only-Headphoneamp)
So - what tube should I get for my (future) EHHA ?
