I have quite a few of these tubes. Anywayz, my step-son is moving into his first "real" place and I decided to build him a valve audio amp and a set of speakers for a house-warming (pun intended) gift.
I've been tinkering around with just the 6146B (just driving it with my iPhone) and I'm quite pleased with the sound.
I plan to drive the 6146B with a 1/2 a 12AX7, so more to follow.

I assume from your ID that you know how to keep a 6146B tame in an RF sense? As others sometimes discover, a good VHF valve does not always realise that we only want it to amplify up to about 20kHz.
Haha. Yessir. She's tame and these critters can go on up to about 200mc if I remember correctly.
Got her running class A and it sounds great and "she's running real hot old man; real hot..."
But the room smells great.

Now your showing your age.....
N4BBQ, "220mc", you know a lot of these new younger kids in this audio forum may not understand megacycles..... I remember when 220mc was a big deal. Hope you enjoy working with the 6146 tubes as I have a fond memory of them. W7KXW (aka Mickeystan)

I'll tell you that glowing plate makes me want to build up an AM transmitter. That'll be a good project for retirement.
My step-son came in when I was working on the "prototype" and he was grinning ear to ear.
Thanks for chiming in. Maybe we'll meet on the luminiferous ether one of these days.
Well I found a few 6SL7s so its out with the 12AX7 driver, and in with these. It sounds pretty darn good, although the OPT I'm using is a power transformer from a UPS (125VAC/16VAC).
I have some Edcor ones on order. They should be here in a few weeks.
I really like the 6146, with the exception of the low screen grid voltage.
