No but I have a spare one. Might also have a spare of the bigger ones... I've been asked this a couple of times now but would people want a simpler power supply for the KGSSHV? This one is a tour de force and there are ways of just bypassing the complicated stuff but perhaps it would be a good idea to have one that is simple and foolproof. For instance, if the old Blue Hawaii power supply stopped working it was always the same fix, replace the mosfet.

Somebody sends this man money while not being under duress? Holy fuck people are gullible...

I use pink varnish as that's just how I roll but apply it in layers for a very good barrier. There are also insulated 78xx/79xx that we perhaps should put into the BOM. Saves hassle but the new PSU board don't have any sinks for the LV section.

Carbon is an excellent conductor so clean all that off and seal the exposed copper somehow. Glue, varnish, something like that.

Yes, distortion is a wonderful thing. There was a good USB comparison in the latest Hifi News...

That was excellent. Here is one that took me minute to figure out the first time I heard it on the TV:

Andy is in trouble if I'm ever in So.Cal...

You do know that I was going order for you... If that's all you want then I'll send it in right away.

Just got a brand new SRS-2170 from Japan and why do Stax always do this, make the base model so bloody good. The other Lambda models always have some issues (too fucking bright being my biggest issue) but this one is brilliant even with the SRM-252S. I guess it is their way of making the more expensive models sound "better" but for fucks sake...

There has to be some ancient order of soldering monks that teach this shit as I just don't know how to do it this badly. Needless to say, that PCB went up in flames even after I tried to fix it...

This is a good example of how you should not solder a diode in a +/-500V supply.

This is about as simple as it can get but care has to be taken when soldering in the tubes. There are no cheap sockets available for sub-mini's so they have to be soldered in. I didn't care enough to make a new footprint for them so this is a TO-5 base which is quite small. Should be fine with non-Hennyo solder skills.

They are certainly the best dynamic ever made, I brought the Senn dealer here an impedance adapter this week for them to try out. They were pleased by the difference but I'll have to visit them again once they've had some more time with it.

Crap!!!! Nahhh... just kidding. The production version is a bit different.

Now something to use with the mini switcher above, a subminiature tube electrostatic amp. The pcb is less than 120*90mm for both channels and it is fully balanced from input to output. Only one B+ for both given the voltage constraints of these tubes so limited voltage swing but who cares... it will look cool.

Better yet, use a phono stage. That's really vintage!!

Sovshiller liked them so I have my doubts...

There are voltage issues at play here so stick with the 1K pot.

Just a tad...

Which version are you using, IXYS or the A1968? Personally I'd only do this on the Sanyo part... As for how much current, until there is smoke. You can also tweak the offset series resistor to give you more range.

Let's put it this way, throw water on the amp and it evaporates quickly enough to not short out the circuit...

Yes but it isn't true as you can do much better matching than the factory job and link the two dies thermally. This guys claim was more than there were still plenty of P-fets to be found in duals as he was able to get some.

I'm a bit amazed you could read that thread. The guy is a bit of a case but in a nutshell he wants a separate PSU for the low voltage section (which draws almost no power) but not for the high voltage (which draws all of the power), less feedback and bigger caps. He also calls the amps cheap in terms of build quality and shames Stax for using single transistors matched into pairs. The guy has clearly never built anything as a product or indeed lives in the real world.

Nothing springs to mind.
