Hi Sonny
I received the output board yesterday with no power jumper. Is this planned to be shipped with the LPS? If not, I will have to buy a Molex crimper and terminals for one connection.

I am sorry. I will send it right away!
Hi vitalica.
They will be ready by next week.
We have changed the size of the heatsink and added a low noise smps before the +5.5V low noise regulator.
But everything still fits in the space
The wrongly made LPS (V1.0) does work but is limited to 200mA on the +/-15V and 100mA on the +5.5V (can be adjusted from +5V to +6V)
I sell the LPS V1.0 to 75€/pcs until the 9pcs are gone.

Hi
We still have stock and ifwe run out we will make more.
Secondly regarding the LPS V1.0
One asked if it was good enough for powering the AK4490 DAC???
The LPS V1.0 is good enough for powering the Discrete preamp with frontpanel or the AK4490 without the frontpanel.
It cannot be used for powering both. Only the preamp kit or the DAC without frontpanel.

With regards to LPS V1.0. What is the ripple and PSRR?
I'm planning to build a MC phono preamp and would like to see if the LPS1 can be used for that. I need 150ma +/- 15Volt, so in that respect the LPS V1.0 would be suitable.

Hi Sonny,New firmware for the frontpanel when used with the DAC only.
Two weeks ago we have made a new firmware for the frontpanel used with the DAC only.
I bought the DAC and discrete board last year.
-any new firmware update?
- for the frontpanel, can I add buttons to select the filters etc?
- How much is for the front panel?
I have a 600:600 ohm transformer and I am thinking of trying it out. Can you also show me how to connect the transformer directly to the AK4490 board? I read somewhere in this thread that the output need a resistor across it or in series with the output? Not sure, but please help. Am thinking of testing out before investing in a Lumdahl.
Sonny, or anyone that might know. The 5.1 V rail, what is it used for? Is it the display stuff? Is it needed without it? Since the DAC takes its current from the +15V rail.
