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.
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...
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.
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
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.
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.
