Hehe . I'm sure you'll get one someday. I should get my octal adapters today or tomorow then I'll give a pair of 6bl7gta's a shot as the output tubes. The voltage is set higher than the stock 300V on my amp, doesn't seem to affect the 5687s much although it wouldn't surprise me if it'll knock some hours off their lifetime. The increased voltage should be great for the bl7gta's though
