I have for sale my Alps 'Black Beauty' passive pre.
I built this awhile ago for myself.
I've used multi core silver hookup wire and quality sockets in a nice aluminium box.
2 inputs 1 output
50k ohm pot with stepped increments, very good channel balance (tracking)
The Alps 'Black Beauty' pot was used by Quad in there excellent 34/44 preamps, and early Naim chrome bumper preamps, before cost cutting began.
£55 inclusive of p&p
