2 x amp boards
1 left and 1 right psu board (left board has onboard low voltage supply, right board has the onboard bias supply)
or
use 1 + and 1 - grlv boards (golden reference low voltage boards) which then gives you flexibility to use 2 right psu boards for pro and normal bias-

Soren Paid.
I reduced my order down to 2 (was 4) GRLV and 2 (was 4) Carbon boards. Let me know if there are any issues from me doing this, I don’t want to affect the group payment differences, if so I’ll pay for the original amount I promised.

... and V6 silkscreen updated to 120ohm resistor (V5 was 182ohm).

Only the left channel then?

If your money's good your fine. Ships worldwide I'm sure.

Very slick chassis and a great build.

Fair point and hereby changed. The golden Reference Low Voltage will be the split board version (the number in that column will comprise a set (left + right).

Just throwing this out there. I like the split GRLV boards. They make layout design choses more versatile. You can put them together for virtually the same footprint as a full size dual board. The only consideration is that the transformer secondaries cannot be CT.

A member here sold his Esoteric K0-1 for the Yggdrasil and hasn’t looked back.

Just for you Erwin (wink).... my next Carbon front panel.
Twos good too

Beautiful builds Geoff.

Yeah those resistors are fine.
Since you have a working board I’d through and compare voltages, starting from the rectifier diodes following the schematic. Just be very careful. -
I can’t see anything wrong. From the pics I cannot tell in the tantalum cap is correct polarity. What voltage are you going for? The resistors look different values in the voltage setting positions.

Or a faulty LT1021.

Both methods work well.
If you want to rational a bracket adds thermal resistance between the device and the heatsink, theoretically therefore not optimum. But excuted well, like most builders here do, there are no problems with this method.

Teaching your grandmother to suck eggs?
Of course this has been covered here a bazillion times. We also deal with high voltage, most papers out their don’t cover this aspect (including the one you’ve reference).

Any chance of psu fat boards?

Have you tightened the vacant terminal block screws where your measuring from?

Just needs a good DAC for 20mA and it's perfect for SR-009s.

Group Buy - Carbon V7.0
in Do It Yourself
Posted
I think Soren has closed this group buy as it’s already ordered and proceeding.
Maybe Soren will chime it and let you know of any spares.
