KGSSHV SUCCESSOR
Am I wrong in the impression that the DIY electrostatic amp scene is really quiet, with no PCBs currently being produced for designs from the last 5 or so years?
Is there a successor to the KGSSHV on the way? I assume it would largely remain unchanged with a few subs for obsolete parts and the changes that would entail?
I'm finding that my new O2 MK1 (earliest version) needs a little more juice than the SRM 007T can provide; even though it still sounds awesome
There is no successor planned and I don't see the need for one. We have altered the design a bit this year but it was simply a response to parts availability not a redesign in any way. We also shrunk the boards a bit to make it easier to find chassis for the amps and added a servo option to the outputs to deal with the natural drift in the IXYS parts. Most recently we did a simpler version of the PSU which is more similar to the one used in the old Blue Hawaii unit. This is purely done as a cheaper option and because it's nice to have something like this around. There have been some build issues with the power supplies as the ground plane is so close to the parts so this has been fixed too.
This is all a bit new to us though as normally we just design, do a layout and then move onto something else. We want to keep the HV alive though so constant rework is needed as the semiconductor companies try their darnedest to shut us down.
Any other new designs would be something simpler so a new poor mans amp design but who knows when that will be.
Most of the time is spent now catching up on other projects or coming up with crazier and crazier stuff. There are also some dynamic amps...
So it's a 2.1mm by 5.5mm connector just like all of the other connectors I have? Sweet.
This is the one and many of these supplies have plug on connectors which means you can reverse the polarity without any cutting/soldering.
