EPI & Epicure Speakers:
The Epicure Model One Power Amplifier

(note: parts and service are not available through me)

Once upon a time, I had one of these. I used it in my factory "listening area," and it ran my factory overhead speakers and workshop speakers day in and day out flawlessly. I eventually sold it, to a very motivated buyer.

Here are two great photos from that brochure:
