I recently bought a vintage tube amp equipped with four 6AV6's as the preamp tubes.

I can't find any of these tubes anywhere in town, I'm assuming they're uncommon. And I don't want to go through the trouble of ordering online and such.

Is there any tubes I can replace the 6AV6 tubes with?

It's not that much trouble buying stuff online.
