Searching for schemo for A@P@I 500 sized BBEQ -3 band swept

[strangeandbouncy]

Studio I used to work at had a pair for a while. These really rocked. Not at all "chippy". 3 Band swept, shelf top n' bottom, broad Q mid, very very smooth. they had transistors driving tranny output immsm. i think they would be great to clone, if anyone has any schemo . . . . .

Anyone?
