Helllo,
I have some questions about transistor replacement. I did found some info on AK but just want to make sure I understand it correctly
-can a assume that trans. in an amp build around 1974 are not available anymore and its gonna be replacements no matter what? is it better to stick with the original or is it like with caps, the modern substitions are better quality?
-if i do find the original ones do i have change them on both channels? if i used substitions that would make sense to me but its not clear to me in case i do find some originals what i should do
-do stores look for substitions themselves if you ask them?
-how do you go about finding substitutions in general? i found some on the net for mine in a 'japanes transistor substitution handbook', i think it was from 1993? is this a good reference?
-i read something about 'pairing', how do you find out if the substitutions match up as a pair?
thanks,
Gerard
