That is right. People forget or just don't realize it is perfectly fine to do. It's extra easy with the Mesas fixed-bias and color coding, because you can even go a step beyond and mix two different models of 6L6 withing the same pair (like in a single rectifier 50w) provided they are the same color code. Like you can pair a single str430 green with a single str440 green.
Where are all the Greenbacks?

The blackbacks are G12H, at least mine are, I am not sure if they used the black caps on anything else. This set has the pulsonic cones stamped 1777. That would make the manufacturer date Feb 1973 to Apr 1974

It’s allegedly the story that blackbacks are greenbacks without the green. I can’t back it up because it’s someone else’s anecdote. Does it make any sense to you?
the 1777 code indicates the 75hz cone, its a celestion code not manufacturer code. there are both g12h and g12m blackbacks, same with greenbacks. just like fender or gibson, they werent going to stop making something because a piece of plastic in the right color wasnt available. cool speakers!

Blackbacks are the just the colour of the speaker caps they were using at the time.
G12M (medium magnet) or G12H (heavy magnet) is what determines the specific model no.
Both models have been manufactured with green, black, and cream speaker caps in the early days.
Re-issue Greenbacks are a tribute to the original G12M models. When people say Greenback they are almost always referring to G12M model no.
