Correct load line. Its a a bit of a niche for long life cool tubes not pushed for current which is usually a noisier situation. Being output tubes they are designed for high swings so when in a line pre we can keep them even more linear.

Have not listened much yet, but the sonic signature is more or less the same.
I think it would be ideal for F5 though, or other low gain amps with highish input impedance.
So I dont intend to be a partybuster here but the Baby Huey has sensitivity enough for line level input. Just for scientific reason it would be interesting to compare your impression on what some would call the best preamp in the world. None at all. You had a TVC dont you?

My phono stage has about 0,3V output, so some gain is required. Tried it with a buffer, but was marginal. If you wanted to rock a little bit sometimes, or with lower level recordings, no chance.
With cd you should be ok.
Also I use the TSSA which has around 20dB sensitivity, and there is a must.
As I was thinking to apply some GNF to the power amp - as an experiment, maybe I like it more - this would drop the sensitivity a little more, so some gain is necessary in this situation too.

Ok. All my signal devices outputs around 2 V RMS and I have a ECC83/EL84PP UL that I rarely put much over 12 o'clock. Is that Salas NJFET RIAA?

I am new to this. It is old but functional. But also needs some adjustments. I leave this for next winter. It is getting warm here now and getting difficult to stay inside!
