I've got 2 pcbs for hamptone mono tube mic pre's. Asking $50/ shipping. I bought these a while back but never got started on them. I can throw some pcb mount tube sockets as well.
Here's a pic I found on the Hamptone site. These look like much older revisions, so I'll definitely update with a picture of what I have. They are supposed to be fantastic and I've always wanted to build a pair. I never even started.
