They do sound good, very "warm" to give them a word, I like warm so good for me. As far as improving the over all sound, I think anything would of improved the sound of my amp after all the miles I put on it over the last eighteen months. I play through a Mesa Boogie Stiletto stage 2, that is coming up on a decade old, for live and recording. I practice through it now and again but it really sounds weak at bedroom level so not too much. They are a little noisy, not through the speakers noisy, but they hum kinda like those old RCA's I used to pull out of old tv's. These don't have near the punch that Mesa or GT's have, nor do they have the clarity, good solid tube very little to no distortion. Have to turn my amp up a little but it sounds better up so I can live with it. The clean channel sings and it is easy to break them up if you apply the right force. I think I'll still use my Mesa tubes for recording, but as many bars and outdoor shows my amp sees a year these are half the price so I'll live with a bit more spongy tone.

Amplifier emitted a loud pop when power was turned on, then made a sound like frying eggs for 10 or 15 minutes. After all that, it seemed to work, but had a buzz in the background. I took them out and put in the old tubes and the amp worked fine. This is the second set of tubes I have purchased from you. I bought a set of 4 Groove Tubes 4 or 5 years ago and they worked perfectly. One of them developed a mechanical noise, so I ordered these. The ad says that they are not returnable, so I don't really know what to expect at this point. I have done business with Musician's friend off and on for a number of years so I'm hopeful this will be resolved.

          Ordered these to replace The Ruby's in a used Peavey Windsor . Tried Svetlanas but tone was thin and output was weak. These brought the amp back to life . Good balanced tones from bass to treble.

              Comments about Ruby EL34 Matched Power Tubes:

              I used a match set of these Ruby tubes in both channels of my 1964 Dynaco ST-70 and they worked fine. Set the plate BIAS to 1.4 VDC per channel. My amp has never sounded better. There were no unusual noises either during breeak-in. I like the larger bulbs, they give my amp a nice classic look.

                    Perfect! Made my Carvin V3 sound extremely full and the volume difference between the old and new tubes was very distinguishable. I recommend these for backups, new tubes or for a friend in need of new tubes!
