| What Does It Take To Surpass A SME V? The mighty ET2 was left out of that exclusive club. Never owned the Triplanar, but have owned the SME5 and the Graham and still own the ET2. In the ways that matter to me, and with the many cartridges of both the MC and MM variety that I have use... | |
| Compact ~20WPC Tube Amp it is simply using the first section of the 6SN7 as a grounded cathode volt-amp DC coupled to the second triode and then capacitor coupled to the 300B grid. This amp does not do the 300B justice (I’ve built it before). As you know a circuit lik... | |
| Peachtree GaN 1 Beta YOU CANNOT measure the sound of solder, wire, jacks....removing jacks, damping, wire directionality, capacitors, resistor brands, inductor brands, removing noise creating things like fuses and LEDs, adding exotic noise filters, etc, etc. into inf... | |
| Compact ~20WPC Tube Amp Either of them (And other amplifier builders who have similar view) are far more qualified than me to debate this point with you. I can say that their comments make plenty of sense and are backed up by their SET amplifier performance results. I j... | |
| Buzzing from speakers on TT rig @mofojo Its really obvious your tonearm wiring has a bad (and intermittent) ground. Is the arm in warranty? If yes, I'd consider sending it back for repair; you might have to do that anyway... | |
| What Does It Take To Surpass A SME V? Raul can be very difficult to translate at times and he has a knack for saying things in what seems to us an adversarial way which he truly does not mean. @mijostyn He also has a knack for saying things in an adversarial way that he truly means... | |
| Peachtree GaN 1 Beta Sometimes you just can't explain why something works when the scientific mind says it shouldn't. I see Picasso and am dumfounded others see his stuff and marvel at it. Audio is like this. @dolfan That was true in 1985 but measurement tech has a... | |
| Compact ~20WPC Tube Amp The main limitation with some SET amplifiers is the choice of weak/inadequate driver tube. Just as you say, this driver needs to be robust. The DHT output tube demands this. He chose the 6EM7 rather than the 6SN7 for that reason @charles1dad Th... | |
| Compact ~20WPC Tube Amp Which leads me to suspect that the 96 db sensitivity rating is exaggerated or (More possibly) the speaker’s impedance curve and load just isn’t suitable for an SET 300b. @charles1dad That wouldn't surprise me at all. The impedance thing is why ... | |
| Compact ~20WPC Tube Amp If you can find a Dynaco ST35, its a lot more linear amp than its bigger brother. But it makes about 17 Watts/channel. SETs tend to have a limited amount of what I call 'usable power'. By that I mean its usually not a good idea to push them past ... | |
| How do you know when your capacitors need replacing on a vintage SS amp? If the amp is over 35 years old, just do it. Caps can bulge, you can have the plastic sleeve on them shrink a bit (an indication its been running warm) and on computer grade caps, there's a little rubber plug near the terminals that should be per... | |
| Most desirable vacuum tubes for SET amps ^^ At very low power levels the distortion of the amp is very low- hence that 'inner detail' you hear so much about. As the power increases distortion rises with it. If you are nearfield yous speakers may be efficient enough that you're not gettin... | |
| Buzzing from speakers on TT rig @mofojo Sounds like the arm tube isn't properly grounded. Try running the wire from the chassis of the phono section to the arm tube itself. | |
| Peachtree GaN 1 Beta Why continue raining on other's parade when you don't agree with their enthusiasm, or beliefs. It's rather confounding. @kitsap2 FWIW, the manufacturer of the amp did get on this thread and confirmed something that @kuribo caught quite a bit ... | |
| Great YouTube on Class A-A/B VS Class D Can't image what might seperate an $800 amp fro a $4000 amp. 'If you don't know, now you know' -Trevor Howard Power supply, chassis, overall execution and where its built. |
