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.

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.

      I've been using EL34 Ruby tubes in my Marshall for years and have always had good luck with them. I also use their 12AX7's for pre-amp tubes. Long lasting, dependable and they sound great.

          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!

          First thing I noticed was that these Rubies are of a larger diameter than the Groove Tubes & Electro-harmonix, but there's a large selection of tubes I've never tried yet: good power tube.

          Great Brittle High Gain Tube

          Ask me a question

          Comments about Ruby EL34 Matched Power Tubes:

          My understanding is that these are relabeled Shuguang tubes. Shuguang are known for having a very good tolerance and quality control standards, so these tubes should be consistent from batch to batch. They are a more grainy/gainy tube, so do not expect the smoothness of a Winged C. I have a pair of Winged C tubes, and I must say I prefer the Ruby Tubes EL34 because of the gainy/grainy quality. Winged C's are too smooth and honest. If you want the true tone from your preamp tubes, choose the Winged C. If you want something a little more agressive from your power tubes, the Ruby tubes are a better choice. I should note that I have not been using this amp at gig volumes, so I can't comment on the upper volume ranges.
          These tubes have been solid for several months to a year. No microphonics. No sound dropping out. No breaking.
          Good value in tubes. Not as smooth as other power tubes, but an overall good sound.

          I have played with these tubes for a few years now in my Hughes and Kettner 100w DUo tone head and they have been through hell playing shows every weekend only having to change them once so far, they have not let down since I started using them.

          Comments about Ruby EL34 Matched Power Tubes:

          I have used Ruby's to replace the stock gt's in my fender deluxe.. They sound incredible!. so,. I took a chance by replacing the 4 power tubes and 5 preamps in my Marshall jvm ... Sounds Just like new! No need to re-bias with the matched quad set... It was financially risky to put them in the Marshall, but they sounded so pure in the Fender so I went for it! You will not be dissapointed either...

                    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.

                            These are very nice sounding tubes, designed for overdrive use and rock tones. They are made by shaugang/sino in china and i havent been a fan of their stuff, but i was pleasantly suprised by these. Very balanced, nice harmonic content, no noise( squealing or filament hum) they dont flab out and go farty sounding at either extreme hi or low volumes, or frequencies(treble/bass). Ive heard some complain that they dont last, well except for old military tubes, not much lasts a long time in the new super gain amps that everyone likes. Its a trade off becasue they are a great price for the tone you get. These really nail the early 70's, civic auditorium/state fair, guitar hero sound,(nice). If you cant afford a set of Winged C , or Tung Sol these are a great option. right up there with the EL34 EH and maybe even a little better sounding. BTW you wont find these cheaper anywhere than here at Musicians Freind.

                            I have used Ruby 6l6's in my Peavey XXX's for years now, I have 3 of them, but figured might as well have one version with 34's in it for a different option. Really opens up the 60W combo and makes it more full sounding. It seems like it is less high gain than Ruby's 6L6's, which is nice because it gives me more range on the dial to work with. I also own the 40W XXX combo and it has always had a better bottom end than the 212 or 112 60W combo, but the EL34's competes nicely now. Almost scared to think what they would sound like in the 40W combo, might shake the house down and set off ricter scales. Worth a try though.
