Agree with tablejockey, the tubes in your avatar have the PrimaLuna logo on them. If your amp is a PrimaLuna, it has adaptive autobias, which makes tube matching less important. Prima Luna says they don’t even have to be the same tube type, which means you could use a KT120 with your KT 88s in a pinch.
If you have a Primaluna and plan to keep it for a while, order a pair of Gold Lion KT 88s and at least one of them should have a perfect logo and you’ll have a pair of backup tubes should you have any problem with your tubes.
