Why is it important to avoid phase inversion? What difference does it make?

If you want to add a "distortion balance" control, well...

Probably no difference ... until you try to reinject the output somewhere in the console.
Remember, it was for use in a studio

Great schematic Yves. I'll give it a try and see how it goes...

Can the 6J6 be used in a series 6.3V heater (is it controlled warm up?). Since I'll need 4 of them, I don't want any trouble...

Dunno, but I bet the 6J6A (if it exists

) is. I'm too lazy to look right now to be sure, but you'll just end up looking anyway so why have two people look when only one needs to.

(Now there's a drawn out sentance, mmm?)

If you really bother about that, use the "DELUXE" way, feeding the serialized heather trough a 0.45 A Constant Current Source.

You could also use cheaper 5J6, with 0.6A CCS. (AES quotes them 2 bucks each !)

And, yes Tim, I've checked that 6J6A existed
