I find NTE's QUICKCross pretty handy when finding transistor specs. http://www.nteinc.com/qc11. Punching in A1137 (aka 2SA1137) in there comes up with this NTE equivalent: http://www.nteinc.com/specs/200to299/pdf/nte289a.pdf HTH.

The part is labelled "ST A1137", it's a TO-92 PNP device, in what looks like a long-tailed pair in the input stage to the amplifier. I can't find A1137 in any searches in catalogues or online (including st.com) and the manufacturers have no service information for the mixer (Studiomaster Diamond) Anyone have any ideas how to proceed?
