J-fet - tube DAC analog stage
Been thinking of trying this for a TDA1541 which has that 25mV max compliance voltage spec meaning no big 20 ohm passive I/V resistors as so commonly practiced. The J-fet adds about -75db 2nd harmonic per spice, don't know if there is a better substitute. It is DC coupled to the tube gain stage.
