Motorola parts for McIntosh MC2205

[meconlen]

It looks like I need to replace a channel in my amplifier. The output transistors appear to be motorola parts numbered

132-133 7439
152 7552
132-134 7426
151 7552

any idea where I could find these or what an appropriate replacement might be?

Thanks

MC2205 NPN transistor replacement

I am trying to find suitable replacement transistors for :



J90 M624 (npn),

I43 M612 (npn).



The MacIntosh order numbers are:

132-090 &

132-143
These are used to switch LIMIT lights on.
I tried to replace them with BC237 but that didnt work.

 

[dreamth]

you mean bc327/337...

This might help, I re-found it a couple of days ago.
