The thing I find both interesting and really refreshing is that this amp does so many things considered wrong by ‘experts’ and yet obviously manages to sound excellent.

Paralleled tube sections are supposed to lose detail and refinement and blur the soundstage. High resistance in the psu is considered heresy by some, and chokes are generally considered superior to high value resistors in this location. Chokes or CCS are also considered by many to make better plate loads than resistors, and LEDs or battery biasing of the cathode is often considered superior to a conventional RC network.

I guess the outcome adds some weight to the ‘it ain’t what you do, it’s the way that you do it’ philosophy of amp construction.

You may be right. We don't know if it sounds excellent; it merely sounds better than other preamps which may be even more compromised and built with inferior parts. It will be very interesting if the builder explains his prefences.

Hi,

very nice indeed :-)

Some questions:

Do both cathodes share the 330 Ohm Riken resistor and 470uF?
Do both anodes share the same 10K resistor!?

Kind Regards

We also don't know which preamp sounded the most like the input signal.

I also built this but with 6463 tubes and AN m2 psu. Sounds very good. Very musical.

Congrats! I like the simplicity of your amp, both the circuit and the build.
