| Crucial TUBE question Also, it's likely that a schematic wouldn't indicate that pin 7 is used as a tie point, so you'd still be scratching your head. ;-) | |
| Crucial TUBE question I wish I were smart enough to know how the filament voltage made it through the diode to power the filaments, but I'm not. ;-) It worked somehow. "I don't know what it is that makes power tubes in the rectifier position have such a big bold soun... | |
| Crucial TUBE question If you want the best possible rectifier for your PrimaLuna, then spring for a pair of vintage NOS Mullard GZ34s. The price may seem off-putting, but they will literally last a lifetime in that preamp, and offer the best possible sound, IMO. For ma... | |
| Crucial TUBE question Are you sure you aren't using the Home Theater bypass inputs? But looking at the underside photo on the web site, it actually *is* possible that the KT150 worked. There's a zener or diode wired from pin 8 to pin 7 on the rectifier sockets, and t... | |
| Crucial TUBE question If the Prima Luna employs two tube rectifiers for a split power supply, as their ad copy says and a photo of the underside seems to confirm, and one rectfier isn’t working, then only one channel would work. So I don’t know what you put in there bu... | |
| Speakers that disappear Some do it better than others. ;-) Planars have been mentioned, Joseph Audio. ProAcs are well-known for "disappearing" and throwing a big, open, coherent sound stage. That's one of many things I like about my old Response 2's. I'm rarely, if e... | |
| Biwiring make any sense? Depends on the speaker. I have *always* biwired my ProAc Response 2's. They just sound better that way--fuller, deeper soundstage. | |
| Integrated S.E.T Amp and Bookshelf Speakers Recommendations Second the Reference 3As. A friend has a pair and loves them, and he's very fussy. He has several amps but the 3A's work well with his Dennis Had single-ended KT66 amplifer. | |
| TAD vacuum tubes? You might consider the new Psvane Horizon series, which are available on Amazon. The EL34-AT is supposedly a pretty good tube. | |
| TAD vacuum tubes? TAD rebrands selected Chinese tubes. In my experience they are more reliable than buying stock Chinese tubes, but are not as good as Russian-manufactured tubes. In another thread I mentioned testing a series of 6L6/KT66 family tubes in my Willia... | |
| Amplifier Power tubes - important to sound? "Curious, I read herein that the feedback level related to the amplifier is important to consider for purposes of evaluating whether it really makes much of a difference to tube roll power tubes. Anyone know why that would be?" I've seen quite a ... | |
| Amplifier Power tubes - important to sound? Just to be clear, I was certainly not recommending anything other than the correct tube type for the OP’s amplifier. I was simply pointing out that the quality of the output tubes can make a difference, in terms of both power output and the amount... | |
| Amplifier Power tubes - important to sound? @jasonbourne71 I’m sorry, what are you talking about? It’s very easy to substitute an 807 for a 6L6 or KT66 with an adapter socket you can buy on eBay. You just have to be careful to observe the lower dissipation rating and keep the plate and scre... | |
| Amplifier Power tubes - important to sound? Yes, power tubes are important, and not just for "tone." I recently tested a variety of output tubes in my Williamson amplifiers. Just to give a few examples, the Gold Lion KT66 produced the most power before passing 1% THD, 22 watts. The Chine... | |
| Amp for Vintage Heresy Speaking of push-pull EL84s, a musician friend recently heard the little Black Ice FX10 at the Tampa audio show and said it "rocked." Might be a good fit here. |
