Is anyone building the KGSSHV? - Page 24

post #346 of 488

Is it (mouser) the nickname of the person who sells KGSSHV DIY parts?

It's hard to guess from the above, but this might be your first diy project, isn't it?

A bit of caution may be in order before you eletrocute yourself with this, please read read amd read even more before you run with this.

Yes it is my first DIY project. I have got a good friend who can help me with it. He can solder it, but we need a parts.

Mouser electronics?=)

I suggest your friend take a look at the link I posted instead of you playing the intermediary role

You might want to consider the 'other place.' They're much more informative than these parts and

generally updated more often as well. Do take caution in buying from the 'right' places,' there's lots of fake parts out there.

 

Lastly, just don't die. Take your time and be careful. :)

This is more an issue with everything that isn't the KGSSHV, all the parts for the modern version are now sold by mr mouser. the IXYS parts are expensive but that's really about it. technically you don't even need to case the thing if you give it a good spray of conformal coating if you are cheap

Good point. It wasn't clear at all which version he was going for, so for, say, the 1968 parts this might change things. I know at the time there was a little trouble in sourcing some  2sc4686a's. Bdent worked out though. Just something to consider.

I may have missed this but where is the 2SC4686A used (I don't see them in the BOM) and what's the benefit of it? The reason is that I still can access the 2SC4686A in Japan.

the 2sc4686 are the original output devices used before the "modernization", my guess is less cap than the ixtd* part

As NoPants noted they're the original output devices. The 'benefit' is a supposed sweeter sound.

Gotcha. I have last year's on and off-boards and also jumped onto the KGSSHvk boards which came out in Sept/Oct. I guess none of them would be able to leverage on the 2SC4686A?

 

Sadly more than 1 year has passed and despite having bought the boards, and transistors from Sato Denki, I've not progressed in my build.

they should work, iirc there are spots for both isolated and exposed-tab devices. even if there aren't just bend the legs to make it work. spritzer has given the blessing on the IXYS "sound" though

 

I'm jealous, you get some good prices on those active devices.

 

What's stopping you from finishing? It's fairly straightforward before casework, the KGSSHVk moreso than the others.

Brain fart. I was referring to the 2sa1968 being sweeter sounding. 

 

You can use either. I don't personally think there's a big difference with the IXY's over the 'older parts'. More drift, but that isn't really a problem.
