TUBE 1: 12,950 Gm/12,600 Gm (112%/109%) and 12.9mA (107%)/12.6mA (105%)WOW!

With the AMPEREX USN-CEP E188CC and E88CC you are going to hear ALL the frequencies passing through your system, the more sensitive the tube the more you will hear. You are using AUDIO GRADE tubes with the AMPEREX E188CC, which have a sonic-signature that reproduces not only the 'odd'harmonics (1-3-5 etc.) but also the 'even' harmonics (2-4-6 etc.) The new tubes made today in China and Russia only reproduce 'odd' harmonics - thats why everyone upgrades to a vintage made tube made decades ago when these rare 'earth-metals' were available in the inner construction of the vintage tube - now these metals are too expensive to use and todays tube-makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music.

..." "Dear tubemuseumusa, Hi, The pair of (E188CC tubes) arrived an hour ago and I wasted no time. It is exactly what you have recommended. The pair makes my Bitfrost/Lyr/LCD-02 sings ! I like em more than the 70s 6922 Mullard on LCD-2. Haven't tried with the other brighter cans; HD-800 & 700. I love them. Thank you. - arharun..."

…"Dear Tube Museum New York, I just received your AMPEREX USN CEP 7308 E188CC USA FRAME-GRID GRAY-PLATE PAIR and I am speechless! I previously considered my Telefunken E188CC as the top of the musical food-chain, but was I mistaken. The Amperex USN CEP 7308 I got from you break all sonic barriers and I am overwhelmed with the difference from the dull sterile non-musical Telefunken which I had previously thought was the best. I am really grateful for all the information you supplied me, the links about how Amperex invented the Frame-Grid technology and the detail you went into to display the actual test measurements of my Amperex 7308 tubes. I had my friend over last night to audition the USN CEP 7308 against the Telefunken E188CC and the difference was quite apparent. The Telefunken has NO musical tone. I actually like the Telefunken 6DJ8 better than the Telefunken E188CC! I can't believe it! With the Amperex USN CEP tubes my amp just disappears and I hear joust the pure and unadulterated MUSIC as it was intended to be! I can't thank you enough, they are everything I hoped for …and MORE! - j.D."...
