| Using digital preamp to tube power amp questions If you want to use a Single Ended Triode amplifier, you will need a speaker with a lot more efficiency! For best results, whatever the power rating of the SET is, it should not be driven past about 20-15% of that value. For best results. | |
| Tube Watts vs. Solid State Watts - Any credence? Gee, in all this time on this thread no one has bothered to mention the most distinguishing feature of tube amps vs solid state amps. That is the lack of the irritating harmonics present in solid state amps.Actually I did allude to that earlier... | |
| Otari or Technics Reel-to-Reel ? Lowrider57, the record plants take whatever media the master is on- 1/4" or 1/2" master tape or digital file, whatever. I say this as a mastering engineer; we have to be able to handle the master in whatever form it takes. | |
| Techinics Sp-10 Mk2a break-in period So in short, to answer the original question, the answer is 'almost nothing to no change at all'.Really the point is that it will likely keep running the way it had been for another 35 years... | |
| Tube Watts vs. Solid State Watts - Any credence? To be more specific, my tube amp has a 1040 joule power supply. In my "un-technical" way, I interpret that as "head room" because my amp presumably can handle short term power demands that exceed its rated power output of 150 wpc, subject to FR, s... | |
| Otari or Technics Reel-to-Reel ? Its a matter of changing out the heads a tape guides, then recalibrating the electronics to the heads.Sony made a pro audio machine (APR 5003) that sounds quite good that had interchangeable head nests complete with guides. It takes only about 5 m... | |
| Tube Watts vs. Solid State Watts - Any credence? Geoffkait's dynamic headroom theory falls apart when faced with a class A amplifier, which can be either tube or solid state. The Dynamic headroom of an amplifier is measured in decibels, and has to do with the class of operation and the amount of... | |
| Tube Watts vs. Solid State Watts - Any credence? I should have written that sentence differently pointing out that output power depends on the topology of the tube - triode vs. ultra-linear vs. pentode with the output power going progressively higher as one moves from triode to pentode. Really i... | |
| amp power & driver sensitivity in multiamp setup Hi Al- got it. I really don't think so, although it would help the amplifier to have lower distortion. He would still need either greater power or a more efficient driver. | |
| How important is the amp? He insisted that it was the preamp & that I would surprised it was the preamp hence his design effort to minimize the distortion from it.Well if we are going to talk about distortion and coloration, preamps make very little of it, often a 1/10... | |
| Tube Watts vs. Solid State Watts - Any credence? Tube amps using ultra-linear mode of operation use a lot of global negative feedback to generate a higher wattage.Bombaywalla, taken either in or out of context its hard to take this comment seriously. I've modified many Dyna ST-70s where the only... | |
| amp power & driver sensitivity in multiamp setup Something that is missed from this conversation:The driver is measured in sensitivity, not efficiency. As a result the impedance must be taken into account; in this case it results in the efficiency being not quite so high. You can't exchange the ... | |
| Tube Watts vs. Solid State Watts - Any credence? The effect has to do with the distortion of the amplifier.Since a transistor amp clips harshly, its obvious when it happens. A tube amp has a soft clipping characteristic (which can be modified somewhat depending on how feedback is used with the a... | |
| Otari or Technics Reel-to-Reel ? You can find a lot of blank tape on ebay. Seems to me ATR is very much in production- a lot of studios are still using analog tape, enough to keep tape manufacturers alive. | |
| How important is the amp? The amp is pretty important, but a lot depends on your speakers. If the speakers are meant to be driven with transistors, its likely you will not hear a lot of difference between amps. But if the speakers are meant to be driven with tube amps, you... |
