Dear All,
I am currently working on restoration for my AU-X11 and have sourced couple of replacement transistors for the AU-X11.
The replacements are for Tosbhiba 2SA968, and i got them from a source telling me that these are genuine.
I am quite afraid and reluctant to go with these spares.
Here are the pictures below:
1. Toshiba A968(Y Rating)
2. Toshiba A968B(O Rating) - Replacement
Few graphs from Peak Atlas DCA75:
I have overlayed the graphs of one good condition original transistor rating Y over the other replacement transistor with an O rating.
BJT: Ic Vs Vce
BJT: hFE Vs Vce
BJT: hFE Vs Ic
BJT: Ic Vs Vbe
BJT: Ic Vs Ib
Most of the graph data matches the replacement transistors i have sourced.
My knowledge is still not good enough to make out the data from these, hence seeking help from fellow memebers.
Can any one please confirm if this data is sufficient to prove that the replacements are genuine?
Or do the replacements look fishy to your eyes, please let me know your inputs.
