spritzer

Yes and it is not subtle. One cool thing, when you solder LED's they light up... The difference in power is not something I've ever noticed, even with them side by side.

Just washed mine while it was snowing, though only slightly.

Anything from the PS900 should be interchangeable as they are pretty much the same device, albeit the 900 has a much nice chassis (die cast). The chisel tips are what I use most of the time though I have pretty much every one they make. SFV-CH25AR is what I've been using for the last few months....

Anybody can do a board run but don't expect one from Kevin and I.

Look closer....

200mb's+ I can get those plans too but this one is about 50$ a month for 200GB of foreign download so why spend more.

That also isn't the KGSSHV front end. It's similar but not the same. If we had any new parts that we could use then an updated BH would be possible.

I really like FiOS...

Pretty much any film cap would work but it's that big as the cheapest caps are often 250V or so and also much more common. This was just lifted wholesale from the KGSSHV board.

Swapping output stages isn't a good idea. The first Stax T2 used this front end (well similar) with EL34's but it would never work.

Yup, that one should be grounded.

No board run coming from us but any of you are free to organize one. There would be a lot of wires running between the boards but yeah, it would be possible. Also, it isn't 100% clear from the pic but next to the heater connector there is a hole in the board to pass the wires through.

Nothing to report really but things are being discussed. Probably reuse some existing shell to begin with.

We should definitely make a headphone. Not that we aren't working on it already...

Nothing wrong with AC coupling....

Yeah, pretty much any bipolar PSU will do.

Yup I have some prototype boards for sale.

They were anodized.

While the tubes will get hot it's above the caps so they won't see too much heat. Electrolytic caps are rated to 85-105°C but film caps can take way more than that.

Here is what I've been doing for the last day or so when time allowed... This one has the tubes mounted on top of the board to make building and testing far easier. This version uses the old KGSSHV transistors and works with both the fancy teflon tube sockets and the standard ceramic/plastic stuff. This gives the added benefit of extra holes to cool the tubes. Boards are 4.7" x 4.7" and as soon as we are happy I'll order some prototypes.

Sadly it's all the electrostatic amps eating up my time. This will be finished at some point though...

It does drive them quite well.

They are nice for the price but nowhere near the US/Euro milspec stuff.

They dry out simply sitting there. ...and on that note I'm so going to put my Black Gate stash on ebay soon.

Marc drew it up (or had it drawn up, can't remember) back in the day and it's basically the front end off the SRM-007t coupled to a CCS loaded quad of 6S4A's. I modified the boards to turn them into a KGST so just one tube per phase and a simple 10M90 ccs. Works well enough but I'll probably put the boards back on a shelf in favor of the ones I'm designing now. This is a part of larger move to possibly make a limited run of KGST amps. A couple of friends have been asking for a mini Blue Hawaii that would be as slim as is possible for desktop use. The KGST is the most logical circuit for that and it would be fun to do a custom chassis with some over the top PSU design in a separate box. The design is pretty much ready in my head but I simply need to find some time to invest in it and see if any of this can be done locally for me. None of this would be cheap though but that's hardly the point when making something cool...
