| Prima luna dialogue 2 tube rolling If the Mullards seem too warm to you; try Amperex. Keep in mind; the more transparent/accurate the tube, the more revealing your system will be of poor recordings, and/or any other weak link upstream(ie- a bright or grainy CDP). Also- anything you... | |
| Inherent Difference - 12AU7 and a 12AT7 EAT DOES make the 12AX7 tube, but it is referred to by the European moniker: ECC803S, which was the best of the best, for that tube family(http://www.gcaudio.com/cgi-bin/store/showProduct.cgi?id=501). The 12AX7, and the 6DJ8/6922(ECC88), are the t... | |
| does amp draw alot of power when volume is zero With a Class D amp; the output devices are turned off(no bias), until a signal is detected= high efficiency/low temps/low current draw at idle. Class A has full bias applied to outputs, ALL the time= low efficiency/lots of heat/high current draw a... | |
| Inherent Difference - 12AU7 and a 12AT7 Some info on the gain characteristics of the "12" family of 9 pin miniature tubes:(http://thetubestore.com/gainfactor.html) I would suggest some of the better/quieter, and longer lasting, European varieties(NOS- Siemens, Teles, Valvo, Amperex, Mul... | |
| Is this what a good preamp does? Mr S is correct. The more transparent a component, the less it masks the negatives, contained in the source material, or whatever is upstream. Inferior components tend to impose their sonic footprint on whatever passes through them, and make every... | |
| "They are here" vs. "You are there" Generally, I prefer "You are there". In this instance( http://www.youtube.com/watch?v=-FTEdn-Xvck ), I'd prefer she were here(Aussie women are VERY musical)! BTW- If you are easily offended....... DON'T WATCH! You've been warned. | |
| Tube amp, more low end Producing the sound of one electric guitar, takes much less juice than reproducing the sound of a band/orchestra, and all it's bottom end. | |
| o-ring size for 12AX7 & AT7 dampers? The max temp ratings I'd seen(way back when), for Viton and silicone O-rings, were 392 and 400 degrees Farenheit, respectively. Not far enough apart to make much diff, I thought. I've still got a package of the Vitons, from the original order, tha... | |
| o-ring size for 12AX7 & AT7 dampers? Hello Magfan: No- never tried silicone on output tubes. I've been using McMaster-Carr's Viton O-rings(size 135) on my output tubes(EL-34, now 6550), for as long as I have the silicones, on the 9 pin miniatures. I've had the same 16 O-rings(two per... | |
| o-ring size for 12AX7 & AT7 dampers? UPDATE on the McMaster-Carr part number. It's now AS568A-116. Like I said: I got mine 12 years ago. What I posted was the number off the bag they came in, then. (http://www.mcmaster.com) | |
| o-ring size for 12AX7 & AT7 dampers? I've been using McMaster-Carr's part number 116 S70, silcone o-rings, as dampers, for the past 12 years. No need to add anything(grease, etc). They handle the heat of the tubes, without any ill effect, at all. I've had the same rings, on and off, ... | |
| Tube amp, more low end Since you like the sound of the amp you have; you might consider adding the Gallo TR-2 Subwoofer to the mix. You would essentially be bi-amping, with a 250 Watt amp, powering the bass. Much more "live" sounding bottom, than any tubes, or tubed amp... | |
| Tubes in VTL SuperDeluxe Preamp? You could call VTL at (909)627-5944, or e-mail(mail@vtl.com),and ask about a manual. | |
| Pathos Logos Tube Rolling? The E88CC is a European iteration of the 6922, and a direct replacement. Are the Valvo tubes known to be good? Have you replaced the stock tubes, to see if they will still power up? If not: Is there a separate fuse for the tube stage, that may hav... | |
| matched quads, one dead, then what? One of the reasons I purchase my output tubes(matched octets) from Upscale Audio, is the fact that they record all the measurements on the boxes. That would make it a piece of cake for Kevin to perfectly match any tube that had prematurely failed.... |
