Gear for sale

My custom amps and preamps

I am semi-retired, but I do produce a few prototype units, and now and then I have something for sale.  If I have something it will be listed here.  I am NOT taking orders to produce new equipment.  My current designs are being manufactured by Spatial Audio Lab in Utah.  You can see them here.  I also have a new project for all directly heated tube preamps and amps with Joseph Crowe audio in Ontario, Canada.  You can see those products here. Currently I have: Prototype of a fully balanced KT88 push pull amp $4,999 US$ or $6750 Cdn This is a superb KT88 push pull fully balanced amp.  The protective poly can be removed from the transformer set by the new owner.  I left it there to avoid any scratching of the stainless steel.  All transformer coupled, no coupling caps.  KT88 tubes are auto biasing.  Driver tubes are 6V6 and input tubes are 6SN7.  There is also a pair of VR150 (OD3) voltage regulators that isolate the input tubes from driver power supply.  The KT88 tubes have their own power supply.  As with all my gear, all power supplies are fully regulated, and so is the filament supply to the input tubes.  Amp produces 60 watts/ch in ultralinear mode, and about 30 watts/ch in triode.  Comes with Linlai KT88D output tubes, a lovely quad of old stock Russian 6V6, and Shuguang WE6SN7 plus input tubes. NOTE:  This is a fully balanced amp.  It requires a true fully balanced XLR input to each channel.  You cannot use a single ended (RCA) preamp with it.  You could use adapters to create a fully balanced XLR from RCA, but they have to be transformer coupled.  You would not hear what the amp can really do with that solution though.  You could drive it directly with a DAC/streamer with XLR output.  It is pretty sensitive and about .75V input will clip it.  The case is solid walnut.  If you need a fully balanced preamp I do have one old case left (cherry), and could build a 6SN7 based fully balanced preamp for $3995.  I will only consider doing this for the person buying the amp so please don’t inquire about a preamp alone.  So please, if you do not have a fully balanced source with XLR output, do not buy this amp.  The Spatial Audio Lab Raven preamp would work very well with this amp as well as the new preamp from Joseph Crowe Audio. I will warrant it for one full year to the original owner.  I stand behind anything I build. I would prefer to sell it in Canada, but will consider selling to the US, but any tariffs would be your responsibility.  It should be tariff-free under CUSMA since it is made in BC, but that is not always the case depending on the current whims of those in power.
