    Loud pop as tubes warm up - MC30

    Just received my "excellent condition" flea-bay MC 30s. I love them with the La Scalas but they are a bit less than excellent, besides the two DoA tubes when I start them one generates a VERY loud pop through the speaker about 10 seconds into the warm up. No pops, static or cycling after that...
