I assume all of the 300B amps on the list have output transformers or output capacitors (one of them might have both). Of those with transformers, can any of them take a 5,8V balanced input signal (and run properly with it)?

Circuits should be fine running your May unless specified in limitation and also considered in the topology as many tube amps aren't balanced.
Well, the output level can be dropped but I would prefer being able not to do that. 300B amps typically have single-ended topology but those with XLR inputs do balanced to single ended conversion one way or another. My impression of transformer-output tube amps is that most of ones with XLR inputs may be designed to run close to the 4V spec and the transformers would be the most limiting components for the input voltage range.

4V to 6V is a common range but you are limited to the quality of the input transformer.

When the tube is cool to the touch, give it another 5 minutes, then you're ok.

I admittedly have NO patience and pull tubes in a minute or 2. I don’t endorse this practice, it’s just me getting antsy!!!

Torq is selling the mother of all 300B (and 2A3 and 45) amplifier excess... I can't justify it, but someone can, I'm sure!

No, I really do and have for many years
Ah schiit, that's some serious ants in your pants. I hope your joking? ...
I do wait a few minutes before rolling in other tubes, however.
The metal base tubes can get a little bit toasty and get your attention when not given time to cool

NICE
I’ll add that to my tube rolling routine!!
What could possibly go wrong???!

You roll in Elrogs, you roll in MELZ, do not pass go do not roll.

I would personally not buy that.
If I had 15K to burn I will instantly buy Western Electric 91E
This is what I would call the mother of all 300B.
The true mother.

I was on the list for that amp and backed out. It's in general production now. They have them in stock so no wait. They undersold. Big time!

You were going to buy the 91E?!
I was lurking the 91E when it was going for $13,000 or so. There was a special early bird promotion.
