  1. You pay for the iron more than the watts and don't forget build quality, true 240V design, and durability. The designer is on the end of the phone and can repair and upgrade quickly with well chosen parts and without worry. Independent of these advantages 15 watts will sound about 3dB quieter than 30 watts, I doubt it would be a huge deal breaker as valve watts appear louder than solid state watts anyway.

  2. If you have irregular voltage then what you need is a regenerator, not a huge, buzzing safety risk that will not regulate the voltage anyway (unless it has additional circuitry in which case its closer to a regenerator, though still unsafe). They have a place in hospitals and such where equipment is designed to exploit the benefits of it, and safety standards throughout are much, much higher, but not for consumer electronics that are usually designed expecting an earthed neutral wire. At best you can get away with it. Sent from my BLA-L09 using Tapatalk
  3. For 'affordable' tube magic just get yourself a Leak Stereo 20 or a pair of Quad 11 monos. If the components have been sympathetically renewed the amps will last decades without attention. My remaining very early Quad 11 amp has worked without any repair and still on its original power valves, since 1953. Sent from my BLA-L09 using Tapatalk

    They are pin compatible but not equivalent substitutes. Simply put, it will screw up your circuit. It may well be you prefer it that way, I have no opinion about that. Sent from my BLA-L09 using Tapatalk
  5. Frankly many here may be disinclined to trust your profession of sympathy. I suggest if you want a man who won't keep his head down, knows his shit from any direction you look at it, and has an uber high end system (yes even by City bankers standards) contact Kevin at Definitive Audio. That woman's bonus wouldn't even buy his loudspeakers. He's in Nottingham but it's a good day out. Don't take your wallet! Sent from my BLA-L09 using Tapatalk
  6. If you're on Paul's Christmas list ask him if the inductance of the wire wound pot will interfere, it might. Sent from my BLA-L09 using Tapatalk
  7. Sorry I don't know, but if in doubt and no better information available just get one of a similar size from Farnell or RS, there's not a lot of risk tbh. Sent from my BLA-L09 using Tapatalk
  8. Yes, a 50 ohm linear pot. Make sure the power rating is adequate for the new pot. Sent from my BLA-L09 using Tapatalk
  9. If you are careful then it is not significant. If the base is very loose it may be worth checking that none of the wires has become twisted or detached from the pins/snapped. It is possible to reseat the glass using special adhesive, Jac music has links to some. Sent from my BLA-L09 using Tapatalk
  10. If you can show that the effects of the cable on the signal are swamped by the noise in the amplifying chain (and cables) then the burden of proof shifts from 'can it be audible? ' to 'how can it be audible? '. The reason for the debate is, as usual, that many in the hifi community believe cables make a sonic difference, some say 'night and day' difference, other people say nonsense, many sit on the fence and laugh. The point of the exercise is not to convince measurists that cables make no audible difference, it is to explore what differences might exist, and in a context that a subjectivist might find relevant to them, to address their argument instead of trotting out unconscious bias, poor auditory memory and other concepts that, although quite valid, sound pejorative and just harden the subjectivist/objectivist divide. One common subjectivist argument is that sine waves, bleeps and honks don't sound like music, and failure to demonstrate cable differences from such experiments thus remains irrelevant to a subjectivist position. So use music. But cut out the uncontrollable variable in the equation; that bit between our pairs of earlobes. Most subjectivist don't argue that measurements aren't valid as measurements of something, they argue that they have little relevance to their perception of music as played by their kit. So if we make the measurements more relevant to their argument maybe we will find something that explains why they believe this? If not there is at least a valid attempt to address the matter from their perspective, and quantify the differences that do exist between cables when playing music through their kit.

  12. But if the difference is demonstrably negligible how will those who believe otherwise treat the result? If as another example of a deep conspiracy theory to exclude cables from discussion then so be it, but if as an example of a genuine attempt to investigate cable performance?

  13. Surely (if one could be arsed) we could take a music signal out of a low noise amp, put it through the two differing interconnects/speaker cables, and use them to drive a high resolution differential amplifier? If we then output the signal from that onto a DSO set to Hi-Res or Peak Detect mode? The null hypothesis is that there is no difference and any aperiodic response on the 'scope that exceeds the averaged out noise level of the chain will indicate that there is a difference and the null hypothesis is simply disproved. If there is none then to all intents and purposes there are no measurable differences when playing music which is a very high hurdle of proof, and which would be an immensely more reassuring criterion to most subjectivist hifi lovers than frequency sweeps &c. If there is any difference then its time to investigate further. Simple, reliable, repeatable, and achievable. It is not as though there are NO differences between wires, it's just what are they, how big they are, and do they matter to us in our hobby/profession? Can you hear these differences? Meh, I don't care: you say tomato I say tomato.
  14. Bryston are a Canadian brand with strong studio following, and a 20 year guarantee. Canary Audio are a top California outfit for tube amps and Conrad Johnson for s/s and tube amps.. AR, Krell etc as others have mentioned. Frankly you've got more amp choices, and cheaper not just US exchange rate but the Chinese imports as well. And then there's the Shindo/Kondo/Yamamoto/Hashimoto/ Airtight/etc imports from Japan, easier for you to get. The only thing not so easy is British voiced speakers, though Harbeth (and I dare say Spendor, B&W, and Kef) have dealers for their excellent products in USA... Sent from my BLA-L09 using Tapatalk

    Maybe because it comes over as a guitar amp type question, and it's the wrong forum if so? I don't have an answer but if we ignore the circuit and talk Web type generalities then avoid Telefunken, Tesla, EI Yugoslavia, which tend to be described as sounding on the neutral or 'cold' end, look at Mullard, Philips, Valvo, JJ new production, and some of the newer Chinese offerings get good press. But really nobody can answer unless you tell us what amp it's going in. Sent from my BLA-L09 using Tapatalk
