Nearly all Japanese numbered transistors (2SA, 2SB, 2SC, 2SD) have the collector as the center pin. Knowing this, it is a 10 second job to locate the base and emitter with the diode test of the meter.
If the base is the center pin, things get harder. You need an accurate data sheet, or a transistor tester of some sort so you can ferret it out.
As far as this statement:
The Data Sheet at
http://www.fairchildsemi.com/ds/KS/KSC1845.pdf shows the ECB pinout. The guide at
http://www.audiokarma.org/forums/sho...&postcount=411 suggests that for NPN transistors, Emitter goes in the direction of the arrow, Base to the opposite and Emitter to the remaining hole. The unit in question being a to-92, have I installed it wrong? If so, what are the correct designations? If you answer that, I can see my mistake much more clearly.
...I have very little idea what you are confused about.
One, forget that pic you have posted. Forget it. It is maybe useful to determine what the case style is, but I do have a
more comprehensive pic.
As with your pic, it is useful to identify the case style, but
NOT the pinout. Manufacturers decide for themselves where they want to put the emitter, collector, and base. (Note that with power transistors that are commonly attached to heatsinks, messing with the lead arrangement is a LOT less likely, and with the very large power transistors, almost unheard of. But NEVER ASSUME ANYTHING! Check for yourself!)
If you cannot identify the base, emitter, and collector on a physical part you hold in your hand, AND you cannot identify these same transistor leads by looking at a schematic symbol (which is what the the quote above kinda sounds like), I'm afraid that your chances of repairing this receiver are remote in the extreme.
In the off chance that there's something about the schematic symbol that is confusing you about the location of the emitter, I offer this pic:
(the arrow does not point to the emitter, it IS the emitter, and points in the direction of conventional current flow (positive to negative)
