| Phono preamp or SUT for low output moving coil I don't see why this is a question. There's no problem having enough gain with either tube or solid state with the cartridges mentioned. As long as the input of the phono section is properly designed its plug and play; no need for an SUT. If you ... | |
| Right channel phono stage tube goes noisy When I swap the left and right channel tubes, the noise goes to the left channel. @earthtones This statement suggests that the tubes you installed in the channel in question were in fact defective. I've never seen a fault that could cause a tu... | |
| Tube selection 12AT7 and 12AX7 - preamp Regardless of the brand or source, when you use tubes in high performance tube equipment the tubes should be vetted. They should test good on a tester and then they have to be auditioned for noise, microphonics and crackling. If these things are ... | |
| Help find an amp for Soundly speakers @jchiappinelli We showed with Dynastats at the summer CES in Chicago in the early 90s. We used our 60 Watt M-60 amplifiers, which had far more power than we could use in that room. So I think you don’t need a particularly powerful amplifier but ... | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode :) and now that turns out to not be your experience. Kinda makes my point. | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode I am not arguing with what anyone is saying; I have stated before that I am illiterate on these subjects. I was simply directly quoting from the owners manual that came with my amp when I bought it. Although he didn't write it that way, is it p... | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode I just took a look at the specs listed in the V12 owner’s manual and under feedback it says "zero." @immatthewj UL operation is feedback FWIW. To know how much you'd have to compare to pentode operation, which isn't an option... | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode @immatthewj You don't have to dig deep on this one. The Dynaco ST70 is arguably the most famous ultra-linear amplifier made although all the Dynaco amps were ultra-linear. | |
| What Power Amplifier Should I Buy? The brands I think of are horrible choices: ZU Audio and Klipsch. @kevemaher I don't see any problem with the ZUs. They easily keep up with the studio monitors @lynn_olson was recommending. The Klipsch, harder to say; if you want the most dynam... | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode Meaning that I guess he probably "voiced" the V12 in triode, but for at least the present moment, I am preferring UL. @immatthewj IMO 'voicing' is a bad practice. I very much doubt this amp was 'voiced'. I think the term ultra linear is marke... | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode So if the manufacturer spends the extra money for a UL winding they would, seemingly, have optimised it for the tube type and circuit. @viridian This assumes that the manufacturer knew about the patent and designed according to it rather than t... | |
| What Power Amplifier Should I Buy? In reality, speakers with efficiencies in the 87 to 90 dB/meter range typically experience power compression with amplifiers more powerful than 100 watts, @lynn_olson To be clear, the amplifier power is only part of that, the other being the lo... | |
| 300B Tube Amps with 15/16 Watts Per Channel? If you use a Hammond, you will never hear what the circuit can do.... @donsachs Great for small guitar amps though! | |
| 300B Tube Amps with 15/16 Watts Per Channel? Or you can simply use speakers that will run happily on 10 watts and build a very simple (well not that simple actually if you consider power supplies and transformers, etc..) push pull amp with no feedback that is flat from 20-20K with very low... | |
| Bookshelf Speakers for Luxman 590axii? @immatthewj I get it. I was looking for a smaller tube amp and I found that SETs that could make 5 Watts aren't small. The amp I'm using can sit on a sheet of notebook paper with room left over. When you compare PP amps that make the same power as... |
