| Peachtree GaN 1 Beta Ralph, You have stated a couple or more times now on Audiogon that you can measure parts....here is your latest: "Actually, a lot of the things in the list above do have measurable effects. The trick is knowing what to measure." You have never gi... | |
| What Does It Take To Surpass A SME V? @dover Thanks for your comments! Based on your comments i think its very possible that I've not experienced the arm with the right cartridge. It is true that you only need 2 connections for a balanced line; since this would leave the arm tube ungr... | |
| To Tube or not to Tube, that is the question This seems to be a typo, did you mean theST35 is a linear triode? @bruce19 No. The feedback is taken from the speaker terminals and then applied to an early point in the amplifier circuit; in this case the cathode of the input tube. In the ori... | |
| To Tube or not to Tube, that is the question @bruce19 The advantage this amp has over the ST70 is twofold. First, the output transformers (if they are the same design as the original) have better performance. The second advantage is a bit harder to explain but I'll try: Like the ST70 this a... | |
| 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... |
