Tremoverb retube- what are my options?

So my Tremoverb desperately needs new powertubes.

I think I understand how the color codes work for the Boogie tubes, but if I wanted to use a different brand like ElectroHarmonix or whatever that brand is, are there any tubes that can be bought in the stores that I can drop in just like the Boogie tubes without having to rebias my amp?

If so, what are those tubes? I'm pretty much only looking at store buyable tubes only, since I have a friend who works in a music store who is going to give me a discount.

I probe all kind of tubes in mesa amps and never needs to be rebiased, the polarizate circuit is strong enough to fits the tube without a bias adjustment.
It is so important that you buy your tubes matched, that is more important that doing a bias set.
Under my point of view, Russian tubes are so great for that purposes
