C3198, and A1266 Replacement
The answer given by  Whit3rd is the answer to the question I was looking for.


  Those are Japanese partial part numbers, 2SC3198 and 2SA1266 would be the full part numbers. C3198 is NPN, general purpose, in a TO92 package, ECB pinout. A1266 is PNP, 80V, also TO92 package, also ECB pinout. Common 2N transistors usually have EBC pinout (that requires some wire-twisting when replacing). NTE () suggests NTE85 to replace C3198, and NTE290A to replace A1266. – Whit3rd
