parts replacment

[timwebb]

i wanted to know if these parts were interchangeable. i came across this site that cross reference parts for u. just wanted to see if it was true.

2SC4672-KTC4379
2SA1797-KTA1666

There's no way to say definitively whether the sub will work or not without more information. Even with more information, it may be difficult to predict whether a transistor will work as a sub. As examples, IRF540 vs IRF540N in Rockford amps. The N version has almost identical specs but rarely works properly. In class D amps, sometimes minor changes by the manufacturer will result in FET that won't work even though the part number is identical. You need to take the time to describe how they're being used (class b or class ab audio drivers, class d audio/switching drivers, power supply drivers...). If you also list the amplifier, that may be helpful.

How are these being used?

i was looking for 2SC4672 and 2SA1797 for the drive transistors for a 2600 brutus... i came across that site while looking for the data sheet.. i cant find anyone who sells them in small quantities.

Audio or power supply drivers?

That's not a complete model number. What is the exact model number of the amplifier?
