Hi Don -
Closest to furthest is Brunoco 300B, Tektron 2A3/45, and the Cayin Jazz 100.
I've got a video coming soon on the Brunoco and Tektron amps.
Brunoco comes with Electro Harmonix and I've also tried
@PSVANE Horizon 300B (very good tube and a step up over the EH IMO). I also tried the new Western Electric 300B's in it. Obviously they were fantastic tubes.
Tektron came with the same and I am trying NOS RCA, Sylvania and Ken Rad 2A3's and NOS Sylvania 45's in it. Will also be trying new NOS 6SN7's in it.
Furthest uses 805 tubes and I already did a video on that one.
