Want to know replacment of STK

abidoon · 12th May 2006, 10:21 PM

Hello

I am fan of STK based amps. I was out of touch from some years. but now when I want to build an amp for me, the STKs are not easily avaiable in my local market (4191 II, 4192 II, 4231 II, 4241). Now I want information from you guys that which chips can I use for an amp equal or better then STKs and easy to build like STK amps.

Thanks

Whoa, do you have any schematics and/or PCBs?

I really wanna try some STK chips! They look so tight and they have amazing levels of wattage!

Replacement parts, I don't know, but if anyone finds it, tell me too!

Have a look at the chip amps forum.
Most popular designs are LM3875/76. People seem to like them a lot and they are easy to build.

Dear sir,

I work as a service technican and therfore I can get a lot of rare parts. Also a lot of STK chips. I tried to search to get a list, but it's just to long.

If you pay the chip(s) and postage I will buy 'em for you.

The company that sell's them is norwegian only, and send's just to norway.
Here is the adress is www.bleken.no

Now, here is what I want: Can you give me a tip of a good stk amp? They look so cool!

Best regards,

Magnus

Magnus,
Nice offer but a word of warning here.
Many of the STK's you buy at ASWO's are not genuine. They are cheap replacements of the real Sanyo parts. Just thought you should know.

Hi Hugo,

Thanks for the tip. Seem's like it is another thing I have to call 'em for.
I always call them to hear the manufacture of their transistor if it is some types that there is made fake parts of. They have never lied to me before. If anyone interested I'll give them a call. Also, some of the STK chips are the replacement for Onkyo, Grundig and so on. Those must be safe?
Thanks again, it's people like you that make electronic's a little bit easyer. Not only for the hobbyist, but also as a service technican.

Best regards,

Magnus

Indeed, they are listed as original parts and if you order these, they order it from Onkyo, Grundig...
Problem is that these parts are often utterly expensive.
Compare these prices to a modern LM chip and you know what to buy.

Hi again,

Yeah, the price is expensive for orginal parts. Bleken is the only one that have Grundig parts in norway. Those are OK priced. I'm not log'd in so I can't see any price's. I have to go to work later(On a sunday of all things...) and I will chek then.
I remeber we bought some NJM2068 orginal from Onkyo becouse they were out of the oem type. When the bill came we got a shock! But they were veeery neat packed. In invidual cardboard boxes, a antistatic and a pinout diagram...
A lot of parts we order are packed invidual... Wonder how much cheaper it would be if they tossed all in one bag.

We are living in a mad world.

Best regards,
Magnus
