Using J11 to connect the raspberry pi, you need to remove three 33 ohm resistors. This way, the i2s is the raspberry pie, but the hdmi i2s isn't available.

@audiozen,
that's what I thought. Will do so, thanks! For future use, I think I make it internally switchable.
If this 2 holes do not fit well into the solder, they can also be filled with heat conductive silicone rubber. The easiest way is to add a memory radiator to the 4701/3301 chip.

Thanks for your fast answer.
I'll check if there ist enough solder under the chips for best heat conduction.
I desoldered the old 3301, perhaps I'll give the old one another chance. Otherwise I'll wait for the new chips.
Greetings
Ok, found it, edit was not possible. :-|
Talema: 9V/25VA 70061k
Talema: 9V/15VA 70051k
Talema: 7V/7VA 70030k
Please correct if I am wrong.
Talema: 10V/25VA
Talema: 10V/15VA
Talema: 7V/7VA
Talema: 10V/25VA
Talema: 10V/15VA
Talema: 7V/7VA
Talema transformers don't seem to have dual AC10V specs. With dual AC12V transformers, be sure to solder the heat holes behind the 4701/3301 chip or add heat sink to the chip. Please note that there are altogether 4 heat conducting holes. Please warm it up first, because the copper sheath is thermally conductive. Also, don't solder it too long.

Check it out. There are 5 heat holes. Please fill in the soldering to conducte heat.

Hi,
the old 3301 was dead. I soldered a new one and everything is OK.

Perfect. It should have nothing to do with the temperature. If it's too hot, it must be damaged by 4701 first.The current of 4701 is much larger than 3301.
... or add heat sink to the chip ...
Tell me which radiator will be the right one. How much space is there for the heat sink?
Thanks
Audiozen,
Sorry if i have missed the information somewhere, but please could you provide the wiring information for the rotary encoder board and IR receiver to the provided looms/connectors.
Best Regards
James.

Fill the heat hole with soldering tin, so you don't need to add radiator.The radiator can use MOSFET heat sink, which is the photo.

Please see the post #55. There is a pdf about it. SK and SK lite are same.
Does the DAM 1021 by default when bought has the proper filters built in or we have to upload them to the DAC? I know the lite version of this DAC has them already uploaded.

The setup kits only choice the dam1021 with four filters in it. Whatever the filter come from. F4 F5 F6 F7.Only the name shown is four filter names from the Soekris.
Hi all,
to answer the question of the heatsinks I can show you this parts, not really cheap but very good ;-)

An externally hosted image should be here but it was not working when we last tested it.

Nice work!Up and running for initial test. Sounding good, only spdif so far....
Don't worry, there are good wiring and the use of LVDS transmission, the anti-jamming ability is very strong. Only i2s needs to be close, so usb card becomes a kite.😀😀😀

Your radiator looks very cool!Is it alumina ceramic?
