One of the output transitors blew in the process. BinaryMikeAug 4, I have these available from a previous project. Yes, my password is: But of course Motorola had to sell 2sd4224 dang semi biz.

They’ve been out of production for many years, and any ‘new’ devices you may find are certainly Chinese remakes that are not to be trusted. BinaryMikeAug 9, Datasheer for your guidance EW! You must log in or sign up to reply here.


I think use MJ, and the other one that I cant think ofcompliment. The post up top has some other numbers, but if I would have known to use the Motorola’s even when these B,D where around I would have used those Mj’s instead.

Your name or email address: I assume you haven’t located a better option? I just want to try and buy the “best” transistors and I am trying to understand some of the differences in specs. Does MCM use a 2sd4224 tracer and die inspection for replacement component quality assurance? Share This Page Tweet.

I was part of the team that assisted in the tweaking of the fabrication process. I created a major fireworks display when my test probe slipped and shorted on a nearby component while trying to adjust the bias: EchoWarsJun 14, Well even better are the mj, or find the datashet number from “On” of those.


Oregon, land of magnificent stumps. EchoWarsAug 9, MayankJun 15, I decided to get MCM’s view on this issue. These are datqsheet replacements for TO-3 package output devices in many vintage SS amps and receivers.

FootFungusAug 4, It might be fun to get a pair and cut them open, if they aren’t too expensive.
