I'm looking for a Drip Ultra British mic pre circuit board. I don't know if they've gone out of production, but they're not responding to emails and I have all the parts.
They seem to do things in short, limited production runs. I wouldn't count on them having more than is for sale on the site right now, EQ-1, STA Level, U73B and Opto7. Emailing is hit and miss in terms of responsiveness.
FYI they were very responsive to me at the beginning of the year and was told at the end of january. I stopped asking after march so you should probably see if you can salvage any parts.
