parts source - Marshall

Where can i find output transistors for a Marshall 8008 power amp ?

They are labeled:

Marshall T65 , 91 , 34

marsh T64 , 94 09

marsh T65 94 09

TIP29CH

Im assuming there is a part that crosses with the Marshall branded chips

Don't remember which is which, but the NPN is TIP142 and the PNP is TIP147.
9134 , 9409, etc, are date codes (year 1991 , week 34 and so on) and not important.
TIP29CH is TIP29C the last H is not important.
Remember to use proper micas and grease, and a screw insulating nipple if necessary.
Use a lamp bulb limiter and no speaker connected until certain it works properly.

The T65 is NPN - replace it with a TIP142


T64 is PNP - replace it with TIP147
