6n16 calculations
Hi all,

I am thinking about an output stage for my (dvb-project) tda1541 DAC. I have an SRPP output stage based on 6n16b lying around, including transformer. If possible I would like to test this one on the new dac. Can someone verify the below calculations for i/v resistor?

Gain for the tube is 20-25 in SRPP
Output for the tda1541 is 4mA, I use 2 so that will be 8mA.

How do I calculate which i/v resistor value to use?

You would need 33 ohm in theory, but then you'll exceed the output voltage compliance of the DAC.
