2sk170 equivalent

Hi all, Does anyone know of an equivalent to the 2sk I deal with RS and Farnell would they have a suitable equivalent? Thanks for your help Alan. Linear systems LSK Not sure who carries it. He has them and can match them to your spec. I got a few set's from him and they arrived quickly and were spot on. He is also a great person to deal with and can help with the correct matched set.

Give him a try. I was under the impression that these were now discontinued but to my surprise they are still listed by Toshiba Unfortunately the 2SJ74 complement is indeed discontinued.

A great pity! BB code is On.

Jim Williams described the 2sk as "cloudy" sounding Rossi Member Germany Posts: The stock FET is individually biased for each mic; the according resistor values are penciled on the transformer cover.

When you change the FET you need to re-bias. I'm not sure how many people actually do that, so the sound difference they hear may be a FET that's not biased correctly.

Quote from: Rossi on March 31,AM. Heres a schematic not sure if accurate Quote from: gary o on March 31,AM. The resistor values penciled on the transformer cover refer to R7 and R8. I don't think anybody really has a data sheet for the russian FETs used in most Oktavas, so it's probably speculation or mere blah, when people say it's bad or slow. I don't know any FET that couldn't handle full audio bandwidth. As long as your mic isn't noisy, better keep the stock FET.

Here's the official schematic. The is almost identical - you can certainly work it out from this. As Rossi points out, two bias resistor values are usually written on the transformer. I have been round the houses modifying the and mics. There was no real improvement. I eventually sold off all the modified ones and kept a pair of stock s, which I like very much.

They sound like Oktavas, and there is nothing wrong with that. Just my opinion. Gus Member NJ Posts: They work and are biased correctly stock. I have worked on a few Oktava s and s and now I would leave them stock until I found something I did not like about them. Quote from: Rossi on March 31,PM.Parameters and Characteristics.

Thank you! Pin out is different, and it depends on the application but recently I used a j in place of an mpf beacis has a great Pinout guide for most trannies made up until a few years ago. It's a good starting place. Pedal building is like the opposite of sex. All the fun stuff happens before you get in the box. RobA Electron Doctor Posts: Quote from: mrbridgewater on April 02,PM.

It depends on what you're building. If you're using it in a buffer, there are better FETs. If you're building it in a boost, there MAY be better choices.

If you're building it in an overdrive, there isn't really a good sub for the J Their gain is much higher than almost every other FET, and their input headroom is also much lower. This means that when you're cascading them, they produce more gain AND distort easier, so you need fewer stages to achieve higher gain sounds. The closest you can get on pure gain specs without finding something truly exotic is the 2SK, and they still only have just over half as much gain.

Also, as has been noted in many threads in recent years, through-hole FETs are obsolete and consequently difficult to source.

They're going to be expensive. But it's a 50c part You can also buy SMD Js and use an adapter board. Chromosphere posted about those recently. Or check out chromosphere's SMD j with adapter board option. I just snagged 20 of em-His prices are good too! Clayford Electron Doctor Posts: Clay. I'll vouch Chromosphere all day every day. Great guy to deal with. Don't be scared, use a good set of tweezers, and pre-tin.

Oh and watch the video. Thank you friends! I have another!
