That's truely amazing craftsmanship. Congrats Kerry!

Agree, great craftsmanship, Nothing wrong with that knob - I like it.

Wow, fantastic build, Kerry!

Really great design and execution, Kerry!

Wow!  What a nice and small KGST!  Just beautiful!

Beautiful! True work of art.

That's a lovely build Kerry, great work. I really like your pursuit of miniaturised builds.

 

Congratulations

Man, I wish I had this skils. Truly an inspiration

Well done!

Just Wow....such an awesome build!  

Nice build, and the condition of that 007 is unusually pristine

Thanks for the compliments.  This has been a really fun project for me.

 

I've been listening to this for the last year or so.  I needed to fix the servo and case it up. I finally got to that

Beautiful work Kerry!

Beautiful craftsman ship Kerry, but your knob is simply too whiny

My replacement SR-007A finally showed up from Japan (landed in Chicago at about midnight and showed up at my door in TX midday...pretty impressive considering the EMS is USPS domestic).

 

I get to use the KGST with a Stax again....woot!  Love this damn amp...really I do.  If it turned into a pizza and beer at 2am, I might marry it.

That's not legal in Texas.

For the power supply, I see that the silkscreen is not marked with extra space for a thermal pad for the FQPF8N80C transistors. Does that mean that I don't need an aluminum oxide ceramic pad for them? I can just use the Aavid TO220 4880SG kit with a metal screw and not worry about it?

those are insulated parts, so just regular thermal washer,screw and nut.

Hi,New here ish,read the forums but Don't chat as I can't build anything to save my life apart from Lego as a kid and weren't much good at that,us men slate women drivers and here is Kerry who can build amps that most of us fellas would only dream of owning,hat off to Ya,are you single ?

And can I just say hi to Kevin Gilmore,the depths of your intelligence is beyond me and if I had half your intelligence i wouldn't have to work in a factory all my life,your a genius and thanks to you I'll be buying one of your designed amps built by spritzer ,I don't think you realise how much you change peoples lives for the better through music

With your brains and my looks we could rule the world

There are two zeners on the PSU board, connected to the FQPF8N80C MOSFETs. The silkscreen shows them as 24V, but a couple of BOMs floating around (this thread) suggest using TZX12D-TR, a 12V diode. I plan to follow the silkscreen, but just thought I'd double-check.

24V is better so go with that. 

My KGST is done. 

 

 

 

What a wonderful sounding small amp it is! 

 

I still need to tidy up my wiring, but really can't wait to hear how it sounds.
