@Nocturnal, yeah they should be giving them to me.
That looks like a decent price. It's showing as AUD620 and I paid AUD850 for mine. One thing to be aware of is the YBA200 has an auto-bias circuit which I heard could be problematic (mine has been modded to remove the auto-bias). [update: this was removed in the YBA200-2.]
The amp has a more or less standard passive tone stack but with a sweepable mid-frequency, a 'scoop' circuit (leave well alone) and a 'resonance' control which affects (iirc) the negative feedback into the power stage. In reality this adds more 'boom', so you can go from tight and 'modern' to full-on 'old school'. There is a switchable DI out, tuner out etc and it will drive everything down to 2Ω.
Some people complain that it's hard to get a clean sound out of it -- it was designed that way. Others find it overly bright, but they probably try to EQ it like an SS amp and play a Jazz.
2-10-2 (TMB) is as about close as you get to flat. I run the mid freq 'range' at zero to give a bit of a low mid boost, 2-10-10 and the resonance control to taste.
What else? They weigh a trifling 19kg, in part thanks to the toroidal power and output transformers.
