I found each tube type has its own charm. 5670, 2c51, 6922, 6cg7, 6DJ8 and 7DJ8
Ahh, interesting, I assume you needed to use an adapter? Also which 2C51? I used to like the WE 396a in the ZDT amp, nice detail and clarity and they are equivalent to 2C51...
i got a bunch of tubes on loan (enormous thanks to @Gazny) . The one i tried yesterday is the RCA 2C51. Ya it needs an adapter. Has a great sense of soundstage and warm fluid sweetness to the sound. going to be rolling the amperex bugle boy 6922 today. At some point i may hunt down a pair WE396a again. I loved how it sounded on my MCTH before
The Amperex 7308 tubes are also great in the SFD and have a long life.
