i have found in a box that i had forgotten about a brand new Crimson preamp pcb, this was sold as a kit as is ready assembled, it comes with original paperwork (this is a used copy of paperwork but original).

Note the following NOT SUPPLIED
requires usual +/- 15Volt psu
Volume pot
Balance pot
Input selector switch

has MM disc stage on board
these were well respected in the day, i built a few of them for different people.

i am open to offers on this one. please ask for more information
