Hey Bob - the Cayin 70T is auto biasing. I went and checked out my neighbor's yesterday and we looked all over the manual and the amp and there is nothing about biasing anywhere. That is what the dealer told us but we double-checked. He just plugs and plays whatever tubes he wants. So if you still want to try a Cayin amp, get the 70T. It sounds fantastic and you can switch between ultralinear and triode on the fly with the remote! You can also try all the KT tubes as well as the EL tubes in it. Really cool.
Also, the 70T for the US market puts out 55W in UL and 27W in triode. Don't get it confused with the asian market version that is 35W in triode, or some such.
Lastly, there have been reports of fake Cayin amps being sold. I would suggest getting one from your dealer to be safe and sure.
