Is AHT still around?

Can someone please tell me whether American Hybrid Technology, the company that made my AHT DM-P phono preamp, is still in business? It's a beautiful phono preamp, the best I've owned (including a Vendetta and an EAR 834-P, among quite a few others), but it broke and I'd like to get it fixed. If AHT is kaput, I'd welcome suggestions about who else might undertake its repair.

Many thanks to any knowledgeable Audiogoner who might reply.
