Well I just got done upgrading my DSL 100. I was having issues with cruddy sound. My amp would sound good for about the first 10 mins or so, and then get muddy and sounding like garbage. I had tried everything. New preamp tubes, new power tubes, new speaker leads. Nothing seemed to work. I read on the forum about bad Output transformers so I guessed it could be that, and even if it wasn't it was sure to improve on my sound.
Well it's installed. It was pretty easy, and if you have ever thought about replacing your transformer I can tell you it's worth it. My amp sounds AMAZING now. At all volume levels, with or without an attenuator.
Go Mercury!!!!
