This is kind of a eugoogly. I have decided to retire my Traynor YBA200. She still sounds wonderful, but I know that the power tubes are on their last legs and it seems like an expensive cr@pshoot to try to find good quality matched sets of tubes these days. So, after many thousands of hours of enjoyment, my YBA200 is being retired. A couple of years ago, I would have spent money on her. But not now. She is still mostly standard configuration: 12AX7's in the pre-amp and 6550's in the power section. I always liked the tone, so I was never interested in trying different pre-amp tubes. The only thing non-standard is a slight mod to the notorious autobias system. I play in different bands that play different styles of music in different venues, so I am generally happy using a decent solid state amp and the PA. In that respect, I don't have a signature tone. Playing at home for my own enjoyment... well, that's a very different story. You really can't beat the glorious warmth of an all-tube amp. No pedal can match that sound. But I can no longer justify the time and expense of maintaining an all-tube head. Not when there are so many high quality, low price solid state options available. So, she's being retired. I will miss her.
