Not a whole lot of fun soldering those by hand though...

Stax used 2SC2291 but the schematic has it hand written on it "or 2SC3381".

One of these days we will have to go SMD or some mix of SMD and through hole.

We can use the Fairchild parts but I don't relish the thought of having to do the matching for a couple of T2's. I might have a line on some 2SC3381's so there will probably be two layouts.

The 009 on the KGST is indeed just about perfect. We will see some further development of that circuit in the future as I have some ideas... The circlotron will come but I doubt many will be crazy enough to build it. The PSU scares me no end and it will be the first amp to have a very specific BOM as you can't just use something at this level.

That would be why you didn't see any spacers, they are inside the drivers.

Kevin will get some TKD's soon as I get my stash shipped from Japan. The 4CP-601 is only about 5000Yen...

I all but abandoned the project when the difference between new and old 009's came to light but I did just order PCB's for it. Who knows when I'll build them though...

KGSSHV/KGST/KGSSHV Carbon etc. all use these.

No way the amp is responsible for that, that was a diaphragm issue. Basically, the diaphragm has to go back in, exactly the way it came out of the driver. That includes the spacers which Stax put there to perfectly align it.

The feet are off ebay but not the ones I actually ordered. Gotta love ebay for shit like that...

I bought 1000 of each type because... well I'm nuts. I've spent way too much on transistors this month though....

She's a classy lady so she said no but her baby sister was ok with it... These two cousins are simply waiting on screws to secure the XLR sockets... Bigger sinks so MOAR CURRENTZ

For fucks sake.... Ohh well, back to finding replacements.

That driver is a bit of an odd duck, a cross between the first version and the look we have to this day. If you took out the diaphragm then you have to make sure that no spacers were moved out of place or that the diaphragm went back in the same way. If not then you will have problems. As for plastics and electrostatics, some are just fine but others aren't really suitable.

Thanks. The black panels are an extra headache to work on but I like a challenge. It's a bit nuts to think about but I've built 20 mini KGSSHV's at this point in three different sizes... That's in about 6 months or so. If I ever send an amp to a show of any kind then it will have a lexan top panel. Heavily ventilated naturally but it would be a nice fuck you to those who hide the internals.

Something new emerged last night.... Does look kinda cool in black.

Mono FTW!!!!

I'd never, ever touch the diaphragm with my bare fingers. Nothing good can come of that. The tape can leave residue which can arc the drivers. You need something that is sticky but takes next to no force to remove.

Here.

Stax always charge way too much for the drivers. Not as bad as Sennheiser but still...

If you want to sell them then feel free to drop me a line. I'd rather open up a set known to be bad rather than open up my pristine one.

Open up the driver and clean it? That's all there is to do plus possibly patch up a hole in the dust diaphragm.

Those should be fine.

Good point, those have to be 1/2W.
