    Which kind of tubes do You prefer and why?
    How do they sound like?

    I'm thinking of replacing my tubes in my Mesa 400+
    I think it uses 6L6 tubes, but I was wondering if I can replace them with different types to change the sound.

    Any experiences with changing tubes are welcome

    I haven't changed the power tubes in my DB 728, but I'm getting close. I've heard really good things about the JJ/Tesla tubes from reliable sources, so I think I'm going to get a set of JJ KT88's to replace my aging Svet 6550's. The Svet 6550's are really good tubes, which is why Aguilar uses them as stock equipment, but I want to try something different. A good online tube resource with lots of links is www.unclespot.com. Spot is a local/Bay Area vintage amp tech that I was lucky to find.

    Good prices for JJ/Tesla tubes can be found at www.eurotubes.com.
  3. Try this site:


    and look under the test results for 6L6/5881 tubes, paying particular attention to the results for bass applications.
