Default SP-14 6SN7 linestage preamp kit SOLD

For sale is a SP-14 from tubes for hifi. PCB is complete and has had around 20 hours of use. The circuit functions perfectly and measures to specs. This is a very neutral sounding line stage and does amazing things for soundstage. Unfortunately it has too much gain for my system. I do like it so much I am building the buffer half of the circuit in hopes of recreating the soundstage of the SP-14. The cost of the following parts was around $620.00 plus tax and shipping.

I am asking $450.00 obo plus shipping.

SP14 populated/tested PCB
4 Tung sol 6SN7GTB tunes
1 Sylvania NOS 6X5GT/G
1 antek as-0507
1 antek as-05T280
2 antek ca-050
2 Audyn Q4 47uf MKP
1 Audyn Q4 33uf MKP
2 jantzen silver Z .33uf 1200V
Instruction manual and schematics

I would prefer to sell this complete as a lot.

Thank you.

Iím actually expecting one of the nutube PCBs that Nelson Pass has so generously given away any day now. Thank you though.

I updated the title for those who are not familiar with the SP-14.
