Hi
My CD player has two DF1704 in parallel per chanel and OPA 2604 for I/V conversion. I want to do I/V conversion with a resistor and use a passive filter with a tube output stage.
What resistor value should I use for load with parallel DF1704s. There's an interesting schematic with this message that shows a tube stage with passive filter.
The CD player I have can operate at 16 - 44 or 24 - 96. Do the low pass filter frequency between the DF1704 and output stage will be the same for both modes ?
Thanks

This is 1K69+1K8. The L/C is for the HF filter.
