Crown CT-410 Output Devices?

Mark A. Gulbrandsen · 11th July 2006, 12:37 AM

Does anyone know what the PNP and NPN O.P. devices might be for the Com TEch 410 amp? Crown has their part number marked on them and the actual types is not listed on the schematic. Or if you would be able to reccomend subs???

Thanks for your help!

IIRC, they're just house branded MJ15024/25.

Thanks! Is there any reason that MJ21193/94 wouldn't work.... those are also 250 volt 16 amp devices.... I happen to stock alot of those.

Addendum:
I just laid both spec sheets side by side and the MJ21193/94 pair actually has a little bit better soa. But otherwise almost identical specs... I wonder why they even bother to make the MJ15024/25's devices

Crown has replaced the MJ15024/25 in many models with the MJ2119X family.

ON Semiconductor still makes the MJ1502X parts for legacy units that people don't want to worry about frequency compensation issues. For new designs the new parts are better, and for the same money too.
