Myles,
I bought a Traynor YCV20WR a few months ago from Musician's Friend. My first tube amp. I only play at home, so the amp is set up in my music room. I notice when I turn the volume up on my guitar and play, the amp will cut in and out like it has a short somewhere. It does this on both channels. It doesnt seem to be as noticeable with the volume turned down. I thought at first it was my guitar, so I tried with my Strat and Les Paul and both encountered the same problem. Since I am new to tube amps, I'm not sure if that is common or not. Does the amp have some type of breaker to prevent it from getting too loud or maybe it's a tube problem. Thanks for you help with this.
