Finally got both the KT77 and KT66 tubes from Gold Lion burned in. Neither one has the tonal density of something like the RCA 6L6-GA, but the GL's do have their strengths. Clarity, focus, detail. And rhythm/pace. They really do boogie!
I've got a pair of Penta Labs KT88's and Gold Lion KT88's burning in right now (using a 2nd system) and they should be fully cooked in the next 3 days. I like to run in every tube for at least 200 hours before doing any serious listening. Some might even go for 300 (like the black treasure carbon coated tubes or the teflon coated Psvane tubes).
