Speedster 840

[nickb]

Had a conversation the other day about one of these. I had to admit I've never heard of. The description I heard was ( bad phone line)
(1) Model Speedster 840
(2) Designed Eric Kahn
(3) Only 50 made
(4) It uses EL84's on the output

Any info of any kind gratefully received. A schematic would be outstanding.

Thanks.
