Hello Victor
The amp looks really interesting
I am interested in joining the preorder list if it's still open if shipping to the UK (United Kingdom) is possible?
Kind regards
Jamie

You can change the headphone impedance/volume levels by
simply removing the front panel and change the position of a
short pin.

Victor, where is the nfb/non-nfb jumper located? If it is located inside chassis can a spst toggle switch be used instead of jumper without affecting circuit or audio?
Has anyone put together the new 8900 kit already? How does it sound? Picked up a 8600 recently, wondering if 8900 comes close. Also, would it be possible to modify the circuit to accept 45 tubes?

Has any one compared the TU-8900 with and without a preamp? Are there any preamp recommendations?
