| Is rectifier tube arcing a problem? So far so good. I will keep observing. Maybe the amps are just more demanding on the tubes, and some of the old tubes I tried are just bad. @gte357s The 5U4, being a directly heated rectifier, is a far simpler tube than a KT88 or like; I real... | |
| I don't want to beat a dead horse but I'm bugged. It seems many amplifiers have lots of negative feedback and they have low distortion at 20Khz. I don't think it is back in the day any more. There are lots of amplifiers on Stereophile and ASR that have very low distortion at 20Khz. Lower than t... | |
| What's a good amount of time to have my preamp unplugged before I swap out tubes? A minute is fine. | |
| Using tube amp with electrostatic speakers. That's not a great situation for any sort of tube amplifier, but it could be made to work I guess. Using Autoformers from Anti-Cables would help. I can confirm that is the case. Once the impedance issue is corrected, the MLs are really fairly ... | |
| Has anyone heard the newest version of the Klispschhorm? Surely, Ralph, your Classic Audio Horns are a different world than Khorns? Have you heard the 75th Anniversary ones? @mglik I was commenting more about the issue you raised regarding sharp, honking sound of the horns Which IME isn't a th... | |
| Question about Cartridge Loading That calculator is a very good tool. Don't you think? Yes. Make sure that you don't confuse milliHenrys (mH) with microHenrys (uH)! 1mH is equal to 1000uH So if you dropped 0.500mH into the calculator when it should have been 0.005mH, you'll ... | |
| New Analog Technology??? 👍 | |

| New Analog Technology??? They’re just lacquers. The only difference that I can sus out is that the lacquer is applied to an aluminum disc vs lacquer all the way through. In other words, it’s more of a hybrid than something new. @gregdude Actually regular lacquers are... | |
| Has anyone heard the newest version of the Klispschhorm? But what about the sharp, honking sound of the horns? @mglik Huh?? I'm used to horns being relaxed and detailed like good ESLs! They can work quite nicely with good class D amps too 😉 | |
| New Analog Technology??? “An Ionic Original is the pinnacle of recorded sound. It is archival quality. It is future-proof. It is one of one. Not only is an Ionic Original the equivalent of a painting, it is a painting. It is lacquer painted onto an aluminum disc, with a ... | |
| Tube swapping question... @patswalker The 6SN7 is plug and play, no worries, as is the 6X5. If you have the Sovtek 6N8S tubes in stalled (made in the Reflector plant) you may find that almost any 6SN7 made sounds better; its arguably the worst one around IMO. | |
| Question about Cartridge Loading If you have a LOMC cartridge, you'll find that loading has little effect on its audible bandwidth. However it can have an enourmous effect on the phono section being driven by the cartridge, if the phono section is sensitive to RFI being injected ... | |
| Power regeneration - good idea? PS audio? Do you think P20 will improve the sound of your bigger amps like MA2 or 3 on P20 regenerator? I ask because you specified that P20 works well with your "smaller" amps. It may well. Our OTLs are definitely affected by line voltage, although the ... | |
| Replacement for Carver Crimson 275 to drive Maggi .7’s Currently I’m using a Bob Carver Crimson 275 Tube Amp that sounds fantastic but hear I reach it’s ceiling while driving a set of Magnepan .7’s, so I’m considering swapping out the amp. I imagine 15 watts per channel might not be enough for any ... |
