A thin sheet of graphene is highly conductive so it wouldn't work as an electrostatic. Plenty of other ways to do it though.

It uses the same circuit as any of the Dynalo amps so yeah. It's more like the GS-1 and older amp Justin made (V2 etc.) though.

Dynalo would be perfect and if you can't find one of Justin's amps then there is always the Sheer Audio version. Kevin had one of those and he approved...

That is true.

They are twice as good...

Could very well be or he still supports the Dynahi/lo projects after he took them over?

We are working on other things but I've built a prototype that I'm quite happy with. I just need to sit down and draw up a PCB and find a suitable transformer.

Yes, that would do nicely.

Pffft, glaciers are overrated anyway... This was done on purpose though to see if the box could dissipate 50W so I would know how hard I can push the KGSSHV in the same chassis. I will change this one though as the PSU caps will not last long at 60+°C. I just don't have any non inductive resistors in these very low values.

I would much rather buy modules from MSB but there is nothing there we can't DIY if we invest enough time/money.

AMB only sells to people using his own boards.

...and it's pretty much done. Runs very hot, front panel at 60°C after an hour. Hardly surprising given 0.8A@12V times four plus the regulators. I need some new resistors...

Where there is will, there is a way.

Pffft on the Sabre, I won't touch anything that isn't ladder based.

Story of the tiny chassis continues: Moved the regulators and swapped out the 3300uf main PSU caps for 33000uf. I also added servo's to the amp boards (modified version of the Dynalo/KG servo) to keep the offset in check. I'm using TL072's now as there were some just sitting on my desk but I'll probably put in some OPA27's. I have some of those on the left. Bought from a local store so European origin probably...

A one off dac would also make it much harder to dismiss the source as something it isn't. We might do a Mafia dac one of these days as we have a very good I/V stage for it...

Well we could use the Darkstar PCB's for something...

The filaments are indeed the big headache. Using AC and a balance pot is possible but I'd rather use something nicer.

What can I say, I like small amps and all the problems they bring... First up is to unfuck this Icepower amp and get this Le Monstre working at reasonable temps..

Ditto. Seem to have been PM notifications but that's working just fine now.

If you use the isolated parts then thermal paste would be fine but you need to insulate the bare metal tabs. No way around that... Here is the same chassis I'll be using for the mini HV: This is a Hiraga Le Monste being test fitted to see just how hot it gets. The regulators get burning hot so I'll probably relocate them to the side sinks and add servo's, Nice transformer hum as well...

In related news I'm working out the details to make a tiny KGSSHV. The box is only about 15*10*25cm so I have to use a BH power supply as even my tiny HV supply won't fit. With 500V caps I should be able to do 440V or something like that.

Happy Birthday Nate!!!

Gotta love chefs... I'm going to introduce bread that is 100% air soon...

Yeah, that should be enough.
