| OHMs law on S.E.T. Amps What I wanna know is why It's always referred to as "an" SET amp instead of "a" SET amp? "S" is a consonant! Sheesh :)I refer to an SET by saying 'ESS EEE TEE'. If mentioned any other way its usually 'single-ended triode'. I hear 'set' far less of... | |
| 30 foot long Balanced Cables to Balanced/RCA Adapters into Amp's Stereo RCA inputs? @elliottbnewcombjr You'll want something to convert from balanced to single-ended at the other end of that 30 and especially 50 foot cable. If you simply install an RCA connector at the output end, the entire connection will be single-ended. You c... | |
| Why would anyone want class AB amp when class A always sounds better ? So, with less than capable speakers and headphones class AB can sound better ? It can sound better even with great speakers! The sound of any amplifier is always about what distortion it makes, and what distortion it doesn't. You can prevent cross... | |
| Need help with a 6AS7 Headphone Amp For some reason the hum completely disappeared. You had a ground loop. They can seem quite tricky and mysterious. Probably what was happening is the way it was grounded had something to do with the gain stages in the preamp- that they were obtain... | |
| Atmasphere mp1 mk3.3 with phono according to the manufacture they stated JJ for the preamp section (6sn7) and for the phono section they recommend the Shugan from China. Anyone with accurate info. This is correct. With any high performance product using tubes, the tubes have ... | |
| OHMs law on S.E.T. Amps why do SET tube amps output wattage decrease with lower impedance loads (speakers) in comparison to SS amps wattage output staying the same or even increasing with lower impedance loads?@sdguyer87 The short answer is that an SET has a high outp... | |
| Tube Amp Repair/Service - Minneapolis/St. Paul - ? @brian_stabingerWe've been doing repairs on the side but we're a bit busy at the moment. If you've not sorted this out by summer check with us. | |
| Need help with a 6AS7 Headphone Amp @steventrusDoing this sort of thing without an oscilloscope is really difficult!But you can use a DVM to help you. Put it on the AC scale (not DC) and see what you measure when you connect its probes to the plus and minus outputs of the filament s... | |
| "Mytek Empire monoblock power amps, with GaN based technology." Our preamps can drive 10K ohms no worries. Our MP-1 and MP-3 can driver 600 ohms no worries. Having said that a 10K input impedance will exclude ARC preamps and a good number of other tube units as well as sources if a passive volume system is use... | |
| Looking for my Final Pair!! .I have done that experiment with all of the speakers I’ve owned in my current home. I have always preferred full range on mains and sub adjusted accordingly by ear 👂. With REL I have a wonderful blending which delivers deep taught bass.@dave_... | |
| Need help with a 6AS7 Headphone Amp The way i implemented this circuit is that i have a long wire that goes from part a to part b to part c to part d .... to part z and back to part a (in a circle) is that ok?Its not the best... Read what I wrote earlier about this. That bit about... | |
| Need help with a 6AS7 Headphone Amp If you are using an AC filament supply, you might want to bias it at about 60-70 volts above ground so it can't cause secondary emission. If the filament supply is grounded and AC, hum seems pretty likely.You could also be dealing with a ground lo... | |
| Class D for a Tube Lover While class D may give a clear very low distortion sound, tubes would always add a notable (for me) distortion that ruins class D clean sound. I prefer to use either pure tube setting or pure SS setting as I enjoy both kinds of sounds. Mixing t... | |
| Looking for my Final Pair!! Again, Raul is using an Appeal to Authority logical fallacy, and again fails to explain why this relates to the woofer of the Cornwall in particular. Both quotes don't really say anything about this particular driver. Its well-known that crossover... | |
| Looking for my Final Pair!! "" Practical example s of Intermodulation Distortion (IMD) measurements Intermodulation distortion can also be used effectively to evaluate crossover designs. If a transducer is excited with a fixed low frequency test tone, for example near resona... |
