| OTL amps, my pick for the tube used. Those 6C33s in the OP are too closely spaced for reliable operation. The 6C33 is a very hot running tube on account of its prodigious filament. We re-introduced the Novacron by popular demand, but its a simple fact that other tubes are a lot easie... | |
| Cassette tape the first link doesn't have cassette tape (or they ran out). I just repaired a tone arm for the owner of ATR Magnetics- she assured me that they do indeed have cassettes. I'm working on a Nakamichi 700 'Tri-Tracer' right now; just for the record ... | |
| Which Preamp Tube is most consequential: Input or Gain The input is where the circuit has to get it right. It doesn't matter how good things are downstream if the input fails to do its job as best it can! | |
| Proac 2.5 Response tweeter upgrade with Ribbon Tweeter? 2. If I want a speaker of this ’ilk’ (2 woofers + Tweeter and crossovers) that needs serious drive power then I would need to purchase a new amplifier. However, I would rather investigate other speaker options so that I do not need to change my... | |
| What are the advantages to a Class A amp & what are the trade offs? Thanks Ralph. Fwiw you have a way of making the complex easy to understand. Are/Were you also a teacher?I have taught a few classes but mainly I think I got that from working in consumer electronics repair while putting myself through engineering... | |

| Cassette tape If you need new cassettes you can get them from ATR Magneticshttps://www.atrtape.com/Many belts, pinch rollers, heads, tires and the like are available from Russell Industrieshttp://russellind.com/ | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong For example, I’ve read that GaN transistors are capable of switching so fast they literally eliminate dead-time and any resulting distortion caused by it.If a designer believes that, its simply because the encoding scheme and related parts are s... | |
| Recommendations for a Phono Preamp Since you don't need that much gain on account of the SUT, a MM phono section will do the job. We make a little preamp called the UV-1; with a phono section its about 2300.00 and its phono section has been preferred over more expensive phono secti... | |
| What are the advantages to a Class A amp & what are the trade offs? Class A is a tool in the designer's box which allows for lower distortion.With all amplifiers, distortion is essentially what causes amps to sound different from each other, moreso than actual frequency response.The reason for this is that the ear... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Calling it a digital amplifier is a lot closer to the truth than calling an analog amp. Not if you talk to a designer of a class D amp :)Switching is a bit different from digital. Digital has bits with which meaning (a sound signal) is imposed- ho... | |
| Name 3 classic mini-monitors worth keeping- Why? Most of the above speakers are nice but not classics. To start with most above are not 'mini' monitors and to be clear I'm not denigrating any of them. Arguably the Rogers LS35a *does* fit that description though. Possibly also the Radio Shack Opt... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong And for the most part in the nCore/ICEpower/Pascal/TI world this is true, though recent amplifiers from Technics blur the line further, with an A/D stage, DSP processing and unknown amounts of analog feedback at the outputs. Yes, that does add ... | |
| Suggestions on turntable to pair with Rogue RP-7 > Finale 300B SET monos > Heresy 3's The Technics SL1200G is a good machine- you can spend a lot more and not get as good.You're going to have to have a phono section too. A good phono section will have less surface noise (with actually wider bandwidth) than a bad one. Most people do... | |
| Will 2 watts monoblock 45 tube amp work for 90db speakers ? think I would be looking for speakers in the 94-98 db eff range for use with a 45 SET amp....they are really about 1.5 watts, 2 watts is pushing them pretty hard. Actually 1.5 watts is about double what you traditionally get out of a 45. You re... |
