Deb and i traveled to andrews nc, not far from us, to buy my adcom gfa555 from a very nice audiofile and diyer from england.
He has pres amps and speakers he has made, one of which is a phono pre board.
I have not seen it, we just spoke on the phone yesterday about it, he just wants 10 bucks ( he obviously is happy to find a nearby audio fool), and is willing to help out.
I know most mount on a breadboard type structure until they are sure it is something they will keep.
I know its tough to give advice before seeing it or knowing what its made of, but any general advice would be appreciated.
