On crown's web site www.crownaudio.com they have that model cross listed with the PB2, They have the service manual and the schematic, I've uploaded a copy also to the Tech-assist members download site also. The maunual listed 'real' part numbers for other transistors but I didn't see any obvous listing for those other than calling them output device. It might be possible to use something like MJ15024/MJ15025 Class transitors but I've never had one come in of that partucalur crown series so it is a guess on my part. Look at the manual and Schematic to see if there is anything usefull.

Uses TO-3 audio outputs but the # is unfamiliar to me. The PNP is a C6492-0 and the NPN is a C-4751-1 . These are not "2SC" numbers. Anyone know what they are rated at ? They have a "crown" symbol on them, not a typical Motorola marking or other. TIA Keith Trumbla O/O B.E.M Electronics Inc. Est.1954 839 Ellice ave.
