For all of you who want an alternative non-tube I/V stage,
Pedja Rogic was so kind and permit me to make a pcb with his circuit.

To get a smaller pcb, i made two connectors for the needed big 10ĩF caps.


Click the image to open in full size.


The PCB will have the following data:

Material: FR4 - 2mm
Layers: 2
Board size: 110x95 mm
Surface finish: Immersion Gold
Copper weight: 70ĩm
Soldermask: Both sides - green
Silkscreen: Legend on top

Out of production

    Antonioo,

    if you want to use two TDA1541A DAC modules parallel, you need only one of the DDNF I/V module.

    Just change the R I/Vīs from 1K5 to 750R (see BOM).
