Anything marked B is for the BJT's and anything M is for the mosfets. The mosfets should never be used really (outside the CCS), the performance is pretty much terrible.

I would order different boards so my order will always have to be separate. Mine are even smaller...

I need to stock up soon on KGST boards so I could order some extra ones plus the standard PSU board. Mine will always be more expensive than the group order though thanks to my crazy standards and Icelandic customs BS.

Yup, N-channel is N-channel whether it is a fet or a bjt. I would just just the That340 though. Even Kevin likes it a lot which has caused us to look into bipolar inputs for some other amps.

Yup, it's very good.

In that same vein, one of my bakers told me about a large vinyl swap meet here over the weekend today. "Biggie, you should go and explain to them why vinyl sounds so bad..."

The prices are getting out of hand but they will come crashing down again. This has happened before...

No, this one won't be released to the public.

I changed my mind... I normally prefer silver but the white on black like this is quite fetching.

I don't think even Antonio can make me sell this one. The heavily modified SRM-007t it replaces will be sold soon though... It's the new PSU for the KGSSHV mini. Same circuit, just new layout which is slightly smaller ,has better thermal management and is easier to build. I use these in almost everything now and it is a cracking PSU.

Having sold all three of my personal KGST's over the last few months I decided to put my foot down and make one I can' be talked into selling. Use a pulled BH transformer that is 230V only (Justin might recognize this one), add a normal bias output and a lovely volume knob by Kevin.

I've thought about it. I could use an extra dac...

Stax were the first to make commercial electrostatic headphones, no doubt about that. There were a few designs that came in the late 60's but most are all but forgotten about now. The old Stax unofficial site was a treasure trove of these but they did also miss a few. The HR-1000 was ok but nothing special.

Never used those.

It wouldn't work in the Dynalo Mk2 but other than that it will work. The new KGSSHV boards have been updated with the MPSA parts in mind.

Most of the Stax sets used A-T drivers so this was never really their "thing".

Yup, that's why it has 500V in brackets next to it.

Stay far away from that AMRG crap imo. They alone are the reason 25% of the SRM-600's have failed while I've never heard of the TKD units failing in any of the other T1/006t amps.

The sinks aren't connected to anything so you can use what ever you like. I do ground them and use the alumina oxide to make it nice and safe.

Only the 600 and 800 had that pile of fail.

Hi there

That's not one of mine. Looks ok though and is probably the Stax "circuit A" from 1968 modified a bit. As for the thermistor, it could be 465ohm so a 470ohm replacement. The higher value makes sense on the secondary but not the primary.

Thanks for that. Better use a smaller pot then and something in series.

What value did you end up with?

Just leave out the last stage. The CCS is changed to a 10M90 (same pinout as the other IXYS part) and use 300 and 1K resistors. The 2SC4686A is changed to the SiC FET
