Thanks SYN08 ,
however when I tried to search they were not complete matches.
The last letter(s) or suffix code does not return anything,
I'm not real educated on the model numbers but I was trying to find "exact" matches.
Do these suffix's make a difference???

They do but, for regular applications, not much. Usually the suffixes are defining device classes (e.g. of beta). Common designs have usually good margins to such variations. But then you may want to check the service manual/schematics. Checking the device manufacturer data sheets and compare the parameters will help as well.

according to my service manual each of the transistors has 2 choices for the suffix code
eg. 2SC1775A E or F
2SA733 Q or R
2SA733 P or Q

, so I would assume that these codes are significant and I don't want to stray to far from the original spec.
If I'm going to refurbish the unit I would like to make it perform at least to factory spec. if not Better!!
