Alternative transistor to 2sk2145

flyboi · 23rd February 2005, 12:58 PM

Hi guys!

Can anybody recommend to me an alternative to 2sk2145. This is to be used in a pre amp driver circuit.

Thanks!

2sk2145 datasheet

Maybe 2x 2SK2881

or maybe 2x 2SK433

Whats wrong with the 2sk2145?

regards
James

Sumtimes there are a clicking sounds from the amplifier at about few seconds. It happened probably ones a week. But it doesn't affect the amp operations. So there is no sound disturbance when playing music. The clicking sounds is from the amp itself. So, I suspect the transistor is giving problem. Anyway, from the 2sk2145 datasheet , it is in a super mini type with 5 leads package(SM5 package). So, the 2 alternative that was given are in a different packages. Anyway, the 2sk2145 is quite difficult to be found over here. So, i'm hoping that if sumbody is using an alternative transistor in the same SM5 package. Most important thing is that the sound quality is about the same or even better perhaps.

Thanks!
