Hi, I am trying to source some power transistors for a bit of studio gear, I can buy 20,000 of them from a trader but I only need a a few, I am looking for two NPN KD2059 Y 411 and two epitaxial ,NPNs D600 Y420 like I said they are readily availble but no one can sell me a few! Cheers dan

You mean this one: [url="http://uk.farnell.com/sanyo/2sd600ke/transistor-npn-120v-1a-to-126/dp/1790325?Ntt=1790325"]http://uk.farnell.com/sanyo/2sd600ke/trans...325?Ntt=1790325[/url]
Regarding the first one; isn't it the Korean version of 2SD2059 ?
[url="http://www.alldatasheet.com/datasheet-pdf/pdf/69925/KEC/KTD2059.html"]http://www.alldatasheet.com/datasheet-pdf/...EC/KTD2059.html[/url] - this one? This is a general purpose 30W NPN transistor. If you can't find exactly this one, there are replacements available. For example 2SD1407 (and many others).

Thanks Mark,

Was able to replace the D600 with an NTE 373, well i replaced twice! as I quickly found the real cause of the problem, a dodgy voltage regulator, lesson learned, will check from that end next time! I must say I am pretty astonished at the poor quality, particulary the voltage regulators in this unit, its from a 'respectatable' well known brand and some of the soldering was shocking, even i can do better!
