In theory, all Mesa tubes are selected that they should run in an acceptable bias range in Mesa amps. It‘s not like a certain amp needs a certain color code tube as the bias range where the system runs in safe specs is quite large.
However, I have not seen any Mesa branded tubes hotter than...
Like others mentioned, try to opt for green or gray with 6l6. It`s the sweet spot IMO.
With el34, green is already near the limit of the tube, when the amp is run in bold/ss. Mesa suggest running the amp in tube rectificaiton mode, when using el34s
I actually have a Recto with a adjustable bias and I prefer it set to about 26-28mA. Going higher will take away the rest of the fizz but leaves the amp sounding to polite. The fizz ads up to the feel of having bite and is part of all Rectos and maybe even all Mesa amps.
And, at a certain...
This is from coldest to warmest:
Red
Yellow
Green
Gray
Blue
White
I can’t tell, what bias ratings they refer to, especially because bias changes, when you use different rectifier and powersettings.
Which two colors do you have?
Afaik, the company that made the transformers for Mesa went out of business during covid. Now they are produced in Mexico.
Note: I am not sure, if this was Schumacher or if there was a supplier change even before production went to Mexico
Yup, if space isn’t a concern I would go downstairs. Though I get it, that recording upstairs and not in a muffled basement sounds nice.
If going the route with the long mic cable, have a look, how pros are doing it. Maybe you will need a buffer or at least very thick cables to compensate for...
Chimps are even worse. They are strong, have large fangs and are intelligent. They usually attack the face, bite off your fingers or go for your genitals.
It`s more to downgrade the oponent in their social strucktures and not to kill in the first place. And all of the above mentioned things...
