Hello, I have an urge to play around the miniature 6N16B and I want to use it as DAC output stage. Ive came accross two schematics that I like.
One is classic SRPP, the second is CCDA or constant current draw amplifier. You have two almost the same stages dc coupled together and one of these stages is anode gain stage, the other cathode follower. The idea behind this is that when signal is at the input, one tube will conduct equally more as the other one will conduct less - so the current draw from the power supply will be (more) constant. I have a question will this work in the reality like this and will it be better than using one SRPP stage?
My powersupply will be solid state, with choke input, and with electrolytic capacitors (maybe I will split it with some resistors or more chokes to high quality final filtration oil capacitor).
Do you really think 6N6P, E88CC, E80CC... are better than 6N16B? I have these tubes at hand.
Cheers, Michal
