- Overall Nice Tubes Review by R.S.
- I bought a quad of these to try out in my Mesa Mark 2, and so far I am pretty happy with them. My original tubes are very old Sylvania STR387's and while these Ruby replacements don't quite match the originals they are not bad for the price. Compared to the Sylvania tubes, the Ruby's have a slightly more mellow top end, which i actually kinda like. I found the Syvanias a little more tricky to get a nice E.Q. on the top end and the Ruby a little less piercing. I also found the Rubys just don't have the rock solid bottom end of the Sylvanias, and they seem a bit less powerful overall. But, all things considered, unless you feel like shelling out crazy dollars for some N.O.S these tubes seem like a pretty good deal. (Posted on 10/6/12)
