I know D used to have one of these, and according to analogguru, it's a member of the Applied, Conrad, Goya etc. family and the missing link between the Goya Fury Box and the Guild FW-3 (one of which I just missed on ebay for next to nothing :doh:).
EDIT (thanks Stu): Trannies are a TI 2n5781 (Si, PNP) and a 2n5172 (Si, NPN).
Pretty cool.
