The way I see it in the schematic you must use one 8v for the motor supply and can use one 5v (supplying all four 5v sections) by removing L4

Perhaps interesting to report Mr. Jung's new shunt regulator, there is a book released where about 13 well-known regulators are tested measuring and listening test, someone already read this book?

If it was in prototype and not in realeased version, I am to assume you did not think it added anything to the sound to have seperates?
With my new Blue ESR meter my BG F 2200 uF reads .01 Ohm ESR before reforming. I guess that's okay, based on what I've read.
In fact it adds, but I had to jump from a 3400euro (Vienna-Acoustics) speaker set, to a 9000euro (Triangle Magellan) to get the difference.
So far the biggest Shiga improvements I found are:
- Tentlabs clock
- separate power supply for Tentlabs clock
- changing S/PDIF output resistors to Vishay VAR-Series "naked" Z-FOIL
- replacing L7808 reg with LT1086-adj. Please add a 47uF tantalum over R50
- add C11 - 1nF silver-mica

I have same ESR meter and for organic semiconductor cap over 100uF/50V I get 0.00
Blue ESR is working at 100KHz.
With advancedevices smat tweezers I get other results, but this is working at 10KHz.

Tibi, you know we all have the greatest respect for what you've done 
, but in the items you've listed which have improved the Shoga, can you describe "how" it has improved in terms of its sound qualities, soundtsgaing, articulation, smoothness etc?
I'm worried that at some point this thing is going to get so good that improvements may become subjective.

I said once and I repeat, I´m not the man to comment my own design/product. Sorry, I´m not a marketing man.
Beside this, all improvements are highly related to the system each of us is using and of course, personal taste.
What I can tell you is that I´m usualy looking for better instruments separation, body and clarity, while keeping musicality. I´m also paying very close attention to attack and decay.

That sir, is a good set of standards. Enough to put your comments into some perspective. Thank you.
The cap forming started last night at 8 PM. I was happy to see that it did not explode when I walked away. Voltage across the 100 KOhm resistor went down as expected. It went down to less than ~200 mV within 1 hour. As of this morning it was down to 11 mV. Wondering how far to push it before I say the first phase is done.
Ha ha! After the forming my BG "F" 1000uF cap now reads 992uF (it originally read 985), with an ESR of .01 Ohm. 
Tibi, with regard to C66, on the schematic you have it listed as a NPO. Is a silver mica better in this position than the NPO?
Hi Tibi,
How do you connect the 100nF to the primary side of the transformer? Is it just connect the PIO to the 0V and 220V on the primary AC input of the transformer?
Thanks
