This is my first DIY DAC streamer build. I went with a RasPi4, TDA1541 DAC board, 6N2P tubes and a modular enclosure. I will list the major components I purchased below.
The system is running Volumio v3, PeppyMeter plugin and Tidal. I replaced all the capacitors on the TDA1541 DAC board with audio grade caps and is setup with no oversampling. The Lamizator tube section uses a PCB I purchased from a member on DIYaudio that I populated with audio grade components from Mouser. I have a friend who machined the front and rear panel of the enclosure. The front left blue button powers up/down the RasPi4 and the red button on the right is only used for the led as the main power indicator. The main power switch is on the right rear and the rear left switch allows you switch the DAC board between the USB input for streaming and the digital input for CD playback.
@akabek i have almost te same system.
Only the DAC doesn’t work.
The TDA1541A.
The DAC sees incomming digital signal, but there is no analog out.
Did you have the same problem?
@Albert1973 I did not have any issues with the DAC. Do you have the same DAC board as I used? I modified mine as I was running tube outputs. Are you sure the TDA1541 is working?
What a beauty is this. I am also planning to build a streamer like this one, only now with a ess 9028 based dac and tubes 12b4a as I/V converter and followed with a ec900. In the anode lines a CCS will be used based on lm317 and IRF840. The balanced output of the 9028 with converted with 1:1 transformer to unbalanced. Output of the unbalanced with a C 1,0uf to ground and the hot-side as kathode injection. My question is how did you manage to get the hole of display on the frontplate?
Kindly regards,
