The combination of RCA 6GU7 cleartops with the 421A is very listenable in the WA3. Liquid smooth jazz....can hear all the keys on Joe Henderson's sax.

GEC 6AS7G and 1959 Novosibirsk 6n5p triple mica...smooth, but a bit dark.

Some Russian lamp is also very good. Such as 6C33C-V, 6N1P-EV, 6P14P-EV and others. The main thing that they were military (ie not OTK).

Psvanes el84 + Lorenz 12au7 - love this combination on Consonance amp driving my AKG k340.
Very musical in the midrange, yet crisp at both ends of spectrum.
Perfect combination for strings, chamber music and vocals.

^ 12AU7 is a great tube….of course it also depends on the amp design too.

With one of my amps I use a 12AT7 which is kind of similar to a 12AU7.

For me, once I find the tube value I like after experimenting, I stick to it and will not change tubes
