Default Built the x10-d buffer

I am quite happy with the x10-d buffer built this month, no hum, and sparkling sound when added in the audio chain.

Yes, I think in this way the filament has time to warm up before the anode goes live

I agree. Too much global feedback and too many capacitors in the signal path.
A cathode follower should be a better choice. maybe dc coupled, with very few components. no GNF (only local).
Yes, a higher output impedance.

Resurrecting an old thread. I have this clone board modified with good quality caps from aliexpress and want to use as a pure preamp tube buffer with volume control. What value of the volume pot should I be using with this X10-D buffer board and I am using ECC82 tubes? I will get the DACT type 21 step potentiometer which I like the most.

thanks

i guessing higher the better. 50k or 100k if the pot goes before the buffer

Thank you, yes the pot will be placed after the source selection and before the buffer. Will plan to get a 50K one DACT type eBay one 23 step ones.
