Time really flies — it's been over 10 years since the KGST first came out. KGST was one of the very first DIY electrostatic amps I ever built, and it's still one of my favorites today. Recently, I noticed that the schematic in the Stax Mafia Google Drive has diverged quite a bit from the latest version of the KGST PCB layout. So, I decided to take this opportunity to redraw the schematic based on the newest KGST layout. Hopefully, this will be useful to anyone who needs a fresh reference. Please double-check the schematic before using it — there might still be mistakes. Component numbers follow the original KGST schematic as much as possible. New parts are numbered sequentially. Changes from the old schematic are marked in red The servo section has been added Obsolete parts like C2240//A1486/2SC1815 have been replaced with currently available ones Attached below is the schematic. Next step: I'm planning to attempt a shrunk-down version of the KGST layout, inspired by @JoaMat great work. KGST_2025.pdf

Fried rice on the flat top is a game changer. And yes, temps can go very high. Just watch out for the sensitivity to ambient temps and wind. They are a lot more affected by that than a regular grill, in my brief experience. I had one very cold morning where pancakes almost couldn’t be cooked.

Almost finished. A classic for a reason.

You might say I follow the strategy of DIY T2 PSU by Kevin. I have two PSU I’m using for all my electrostatic amplifiers. One original T2 PSU and one I made myself basically same as the original but with KGSSHV PSU regulators. Bottom line: I’ve never have bother about grounding strategies. So far, I haven’t had any issues with ground loops that I’m aware of.

1Q84 by Haruki Marukami Fun and extremely long...

the neutrik jacks i used in the diy t2 are actually 4 wires. the connector shell is a seperate wire. i put in a jumper to chassis ground for that wire.

Correct me if I am wrong. The Ground Pin(Pin1) has been connected to the XLR socket shell by default by the manufacturer in some cases. This way, the ground pin should be left unconnected to avoid a looping ground. In this case, the loop may be like this: XLR(Pin 3)-> AMP signal ground - > L bracket - > chassis -> XLR(Pin 3). I just realised the L-bracket is isolated to the signal ground, so it should be fine.🤐 I assumed the amp chassis ground wires are connected to the PSU chassis somewhere, and the amp signal grounds are merged with the XLR ground, and then connected to the PSU power supply ground somewhere.

Two wins.

With Outkast keeping Oasis out of the RnRHOF, there really was only one choice tonight.

I like the idea about to-252. First draft… …have to think about this. XLR ground pin to signal ground on PCB.

Steve's double spatula game was intense!

Didn't take pics, but cooked bacon, hashbrowns and pancakes on the new griddle. Dorothy cooked scrambled eggs inside. Worked fantastic! My assistant griddler (DOTU)) and I made quick work of it, and had fun.

IXTP10M90S can be replaced with IXCP10M90S(TO-252). If KSC2690 can be replaced by something else with an SMD package, we can eliminate all the aluminum oxide isolations. BTW, what is your grounding strategy? Seems like the ground pins of the XLR input go back to the PSU enclosure.

That's very Spanish of you!

Madness - Tomorrow's (Just Another Day)

Tomorrow morning I will attempt bacon, hashbrowns and pancakes. Dorothy will cook the eggs inside in a skillet, as I worry the seasoning is not ready for eggs yet. There's going to be a learning curve, as this thing can get plenty hot! I'm already thinking of shrimp jambalaya, stir fry dinners, fried rice, and so on. Smash burgers for certain!

Love my flattop, Steve. Smash burgers might be the best way to eat them, homemade friend rice is sofa king good, and being able to cook 9-12 pancakes at once is a first world problem, but still glorious to overcome.

Nice job!

The cats broke the glass lamp in our entryway, so I needed a non-glass replacement. Similar to a design I made a few years ago, but smaller and with some refinements.

Tried a new to us local restaurant, Maison Pucha Bistro. Pleasant experience on the food and drink. For anyone in H-town, I would recommend the escargot, beef empanadas, the bouillabaisse and the lamb osso buco. I asked them to make a rye sidecar and they did a great job...not overly sweet. HS

Seasoning the new griddle while it's raining. It's the latest technique.
