Looking at the parts I got for my second build. A very nice kit indeed - thanks TB! .I believe I'll wait for the watercooling part to materialize before I start. As always keeping an eye on things.
Hope to find a quite period where I will change C3 from Obbligado gold+ to Mundorf SGIO's and replace the cooling blocks to standard from what I've been using. As I now have a probably
So far I'm very very pleased with the SQ as is my wife and the dogs. Really, as soon as I put our regular baroque vinyls on they just find their preferred spots and listen - ears up.
One can hear every instrument if you listen for it. It is there...

Oh, yes - forgot - this one has had the dl-103r as a goal all the time.
The next one will be for a special VdH-mc10 at 0,25mV. No - not 0.65mv - 0.25mV

So, what newthinking ideas does exist for the 369's? My experience is that keep them stable and with stable I mean stable over time which encompasses several hours per degree Celsius. I have found that sound vise these changes doesn't affect SQ. But of course - zero drift would keep my mind at peace as well.

Some population, K117 and LED picking. Is 1k in series with triplets and quartets and a 12(,5) V battery supply a valid configuration for picking the leds? I got 7,76 over the leds in this example and 4,74 over the 1 k resistor. 4,74 mA.

For picking the LEDs, first select your Q7, then rig it up as a ccs in series with 2 x 9v battery and the triplet in sockets like you showed. Then you can measure the Vf drop of the LED string in very similar conditions to the actual circuit.
That's means dither a dropping resistors (if you need to lower the raw voltage a bit) or a link.
I can give initial reports that the swap out to the copper jupiters was very impressive. The solidity in space and detail present seemed to jump substantially. Mid bass with drums was noticeable tighter as well symbols. Vocals seem to just flesh out more detail. The tone may have changed a bit. Although it did not seem to be describable. I found I had to turn down the bass in E-Xover and up the treble to present a little more on the higher end. I think it just emphasized a preference for presenting maybe too much mid bass in the covers current state.
Once can't mess around when comparing notes - so I used some nice recordings to listen to as a baseline.
Willie Nelson Red Headed Stanger on Impex.
Willie Nelson Stardust, silver MoFi version 33 RPM
Natalie Merchant Mofi 45RPM.
It makes me realize how much 'potential' the FSP has, given the right parts from needle on through.
Normally a jumper. Or a resistor if the transformer is too happy for final rectified DC value.
