Looks like a very different (simpler) DAC power supply on this board to your old 2011 version which used the shunt regs. What was the thinking behind this?

Still this price?:

dac not chip AD 1865 : 300$

Have: 1x USB + board DAC+ 1 seloctor

PCB IV : 30 $

Shiing: 50

What is Shiing????

It is without transformator???

I do not see Caddock 200R on the PCB???

Voltage for Amanero is from DAC or USB?

You have schematics for exactly this DAC and the IV PCB???

* shipping
* with transformer
* the caddock 200r are optional, there are already 2 Melf resistors onboard. They are just as good as the caddock.
* there is a jumper to use either the power from dac or the amanero itself.

Thank,s Rol,

you´ve bought the kit?

The IV PCB look´s interesting, Quanghao seperated the tubes sockets from the PCB? For what he made this?

I´ve still here a kit of the first End-DAC, the IV circuit might by the same?

Just have the IV PCB for lundahl 1660 with ECC182 stage?

The "old" DAC-end have 6 voltage rail, it wan´t better or was simples to much?

The price of the assabled DAC the Amanero USB is just incluided?

Yes, I just received the kit today.

This time the tubes are mounted horizontally so they need separate boards.

The IV is almost the same, just with some tweaks for tube choices and room for bigger film caps.

AFAIK, the new Lundahl IV is in the work.

The PSU seems to be simpler than last revisions. Still very good, way more than enough to provide clean power for the DAC.

Yes, for $300 there are the Amanero and transformer for DAC section. No stock for the Amanero right now though.

Hi Quang Hao.
I'd like to buy assambled and checked:
1) DAC (AD1865) with Amanero-USB module but without transformer
2) R2R shunt volume without standby configuration and without RCA sockets. Black remote control and red LCD display will be welcome.
Shipping-Poland
I'll do appreciate for quick replay, Marek.
