Isn't it more the case that older is better, since getter frames have no actual bearing on electrical characteristics?

The getter is an indicator of how old the tube is, and Square and D Getters came before the O.

Exactly what I was getting at.

Black vs gray plates being another indicator.

Got ya. I have always wondered this myself, as other than the getter difference the construction looks the exact same. Can the shape of the getter actually have an effect on the sound? I have yet to find an answer, but the square and d getters are always superior, in my experience.

The getter doesn't determine which tube is better. Year of production for the same tube is. Older the better is the general rule.

Footscray '57 halo triple micas arrived and installed, so I'll spend the week breaking them in. Date codes are 2F7, so mid year.

Even fresh out of the boxes, they're impressive, driving a picky pair of HD800/SDR on high gain, balanced.

Could it be that tubes with a square or d getter are assembled with greater precision than tubes with o getters since the getters are not concentric with the tube inner walls?

Good question!

My theory is that it’s because they were less “engineered”, overbuilt and probably use “better” (ie more toxic) chemicals in the construction. Then they got more precise with circular getters, optimized materials (ie cost considerations) and more exacting amplification. I don’t know?!?!

Great theory @ksorota!

Personally, I'll take a round getter anything over any D-getter GE. But that's just me.

Same here unless it's a dimple getter tube.

Time to verify!

This album is killing me right now
I know I posted this elsewhere but man oh man is it good! If you're open to some funk/jazz with a hint of Zappa. Give it a whirl.
