Mesa STR 415

[jnoel64]

I am packing up my house to move and found 2 pair of Mesa STR 415 tubes. I am guessing they came from my father, either from the Road King 1 he gave me, or from his Mark II B. I am guessing the former more than the latter. At any rate, I thought I would give them a test flight in my TC-50 which has been running the Mesa STR 442 (NOS Winged =C=) I hate to say it, but those 442s will not be going back in for a while. These 415s were made by Sylvania, if I have read correctly. Man, they sound heavenly!

415's do sound heavenly! Modern production tubes are good but 415's are in a league of their own. In a c+ or 3+ it doesn't get any better than 415's and Chinese Military 12ax7's.
