new SP10 preamp

new SP10 preamp, fully assembled & tested, $480, plus $30 shipping in USA

now back in stock !

the new SP10 is an incredible bargain, there is no way I could have built this preamp for under $900 
so yes, I have to admit it's imported from China.  But before you turn away, I want you to know I have 
personally and throughly checked this out, it's now in my own personal system.
This preamp is extremely well built, solid heavy chassis, excellent circuit design, and great sound from four 12AX7 tubes.
The assembled/tested/warranteed version will cost you much less than I could build it for.
Included is a remote control for motorized volume (ALPs volume control) and relay selection of four inputs.
One output, no tape loop, no tone controls, just a super nice package that delivers excellent tube audio music.
I'm not selling a full kit, because that would cost much more than this fully assembled/tested unit.
But if you want to DIY, I can sell you a PCB, power transformer, and tubes separately.
Size is 12.5" wide x 12.5" deep x 4.0" tall and it weights a hefty 9#.
