Probably the best known kit of TT's amplifier line. 35Wpc and original tube set distinguishing with its Russian EL84 stack. Phonostage is BYO - not the built-in option.
I originally purchased in 2006 from North Country Audio when Zia's kits had some Canadian and US representation. Meant to pair up w/ my set of Tetra 120u speakers and a Rega P2 for a vinyl only rig. The military life had me travel a good bit and never got around to setting this up.
Just back from Baltimore Maryland's Just Audio techs for an assessment, service, and (finally) tube biasing. Components deliver the goods (esp. caps are sound), and cosmetically it's as I purchased it - save during the recent shop visit while mounting tubes the 'Signature" has all but rubbed off to a "Sig[. ]" under the "Unisis" plate (see pic). Includes original box, owner's manual, and NA outlet plug.
$2350 and buyer covers shipping at actual cost. Open to conversations.
If you're in discovery mode re TT kit - a review contemporary~ish with my year of purchase https://www.soundstageultra.com/equipment/tube_technology_unisis_signature.htm
And TT legacy site here http://www.tubetechnology.co.uk/tt.htm
Which links to online version of owner's manual, etc. And lots of occassional conversations on audio/hifi forums re Unisis soundstage and regard in the tube amp cult.
