McIntosh output transisor substitute

Jrisk · 28th February 2006, 04:11 AM

Hi all,
I'm trying to fix a couple of Mc-2150 that a friend of mine gave, me but all the output transistors are shorted out, Motorola(132209)(204) used to make them but I'll settle with a good replacement. I haven't been able to get a hold of any schms either, looks like someone wants these amps buried.
If anyone knows something, please give me a hollar.

McIntosh pn's are all house numbers for Motorola outputs.

The MC2120 used the MJ15003/04 series, the newer MC2150 used the MJ15022/23 series.

The TO-3 drivers were MJ15018/19 on many newer ones.

Hi djk,
Your subs are bang on. That should do you John.

A call to Mc Intosh service will probably get you a schematic. They are good people.
