Welcome briggo!!

Schematic is here:
http://members.shaw.ca/lauriepedals/ (there is a link for the corrected schematic 1/2 way down the page)

Any general purpose NPN signal transistor will work. If I had to do the repair, I'd use a BC547 out of the junk box.... only thng to watch is pin configuration. The BC547 is different to the original, for example.
