| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? @yoyoyaya I remember hearing something like that too. The thing about distortion is we don't put a weight on the harmonics generated. The higher ordered harmonics are the ones that really mess with the ear- the 2nd and 3rd, hardly at all. But ... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 I applaud your interest in experimentation. Triodes will give a pleasant distortion. But if you want to maintain the feedback you'll need another stage of gain. Another consideration is the tube in triode mode will want to see a differe... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? It is a two camp showdown one camp being group 1, who evaluate through solely having used their experiences of End Sound produced and the impression made on them. The other camp, group 2, who are much lesser in their number than group 1, and are... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? 845 SET can drive some speakers not often associated with SET, power supplies with these quite substantial, around 900V plate voltage with these. With the right speakers a nice 300B amp running top tier 300B tube like the new Western Electric is ... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? What are your thoughts on reducing the bias a bit on the voltage? @rankaudio The power tubes can handle it well enough. But that will affect the distortion signature of the amp but by how much is hard to say. my tech and I will be adding a sw... | |
| Devore O/96 with high powered amplifiers could there be other factors than damping factor? @avanti1960 Yes. The differences we are used to hearing between amplifiers is mostly the distortion signature of that amp. Our ears use harmonics to tell the difference between the tone color... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @rankaudio The problem with using a solid state rectifier in the ST70 is the plate Voltage tends to run a bit on the high side. If the filter caps and operating points of the power tubes are not addressed on this account, it could lead to trouble.... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? I have loved SETS for a long time, but I simply cannot afford a "great SET". And, being retired, never will. @nightfall I’ve yet to hear an SET at any price that could beat a good quality PP tube amplifier. I’ve been investigating SETs since t... | |
| 20 Vintage Amps That Prove They Really Don’t Make Them Like They Used To I owned two of the amps in the article-Harman Kardon Citation II, Dynaco Stereo 70. Compared to the amps I have now ARC, Unison, they are euphonic and transients are slower. They were also lacking in top end, but so were the speakers that were ma... | |
| 20 Vintage Amps That Prove They Really Don’t Make Them Like They Used To @quincy This is an interesting article and worth reading. But the premise of the article is false. There are plenty of amps out there that are built 'like they used to' in that they are built with high quality parts and construction (including p... | |
| 6SN7 Tube Voltages @jaybe It sure looked to me that he did. Don't get anything that doesn't have a suffix and you should be fine. So GT, GTA and GTB are all good. | |
| 6SN7 Tube Voltages @jaybe 'NOS' stands for New Old Stock so I was referring to older tubes. If you're buying from a reputable tube dealer they will pay attention to the suffix of the tube type you specify. | |
| 6SN7 Tube Voltages @jaybe No-one makes a 6SN7 (no suffix) these days so if you’re buying new tubes its no worries. If you buy NOS make sure you specify the suffix and you’ll be fine. | |
| Ripple current Q for amp capacitors I was reading about reforming the large caps. I'm still not entirely clear on a rig to try it, and i've been rebuilding crt monitors and late 70's-early 80's arcade machines as a hobby for 3 decades. But a question I had, and maybe you'd know, is... | |
| Hattor Audio Autoformer Reference Preamplifier @mitch2 To your question, yes. I don't have a dog in the fight either. I'm simply presenting the facts. I'm still curious about this practice as you can see in my first post. |
