Hi Gang,
I'm still plugging away trying to reverse engineer the schematic for my 
HRO-600 synthesizer. One odd component is a 3N111 transistor, which I 
believe to be a PNP dual-emitter transistor designed for chopper 
applications.  I believe it may be bad  (all pins show the same
voltage), 
but I can't find the pinout for it anywhere.  It's a 4-terminal device, 
presumably with a base, collector, emitter-1, and emitter-2.  Anybody
got 
the pin connections and (hopefully) the data sheet for this odd duck.
I've 
never seen dual-emitter transistors before, and am not sure how they're 
used.Tnx!

Jim Garland W8ZR
