I've been waiting feedback from the PSU designer, but it seems this might falter, as he is quoting around 1000 GBP for a 'full monty' PSU, and not mutch interest in doing something more affordable.
I have done a lot of research and have a design together for something much better than the stock/off-the-shelf LPS available
this would utilize the LT1083 type 3 pin regulator in a tracking pre-regulator arrangement, this is actually very good performance, many orders of magniture better than the current SMPS.
We could run this as a kind of 'open source' /group project.
I don't have the resource or time to make the PCB layout or get the kits produced, but am able to do the design work.
Is there any interest in producing this as a group product?

It may prove to be very interesting indeed.

Hi Grog,
I suspect that Meridian�s awakening to benefits of Linear PSU�s may put a dampener on the interest of DIY kits. I know it�s currently only for 800 series, I guess Meridian will see how sales go before looking at options for G series.
Regards,
Carl

What ever happened to this potential project? My G68 is blowing mains fuses when powered on. It apparently blew initially in standby mode.
BTW, I think it's only a PS issue.

Hi, welcome to the forum.
In the U.S. there is an "out of warranty" service provided by a very knowledgeable ex-Meridian employee, Marc Koval. He upgraded the power supply in my 861V4 and there hasn't been a hiccup since.
There is also plenty of documentation in the forum if you are more of a "DIY" guy. (Search WelwynNick).

With Meridian providing an 861 linear PSU, Healthcheck and five year warranty for around �500, it was a no brainer for me.

Was that for an 861, or does Meridian's linear PSU fit in a G68?
