Just wanted to get a feel for what owners are using. I've had my Clubman for about 6 months, and it's definitely time for a tube swap. I've heard these amps eat EL34's and apparently that's true. NOS is out of the question if I'm going to replace them a couple of times per year. It came with JJ's, and will have a set of Ruby EL34BSTR's next week. I like Winged C tubes, but they are the priciest of the New Production tubes. What are you using?
