| Step Up Transformers….Are they Worth the Trouble? All audio transformers have to be properly loaded. This is important so as to allow for the flattest and widest frequency response. The correct load will vary with the source impedance (the cartridge) since transformers transform impedance (they ... | |
| Can an owner's manual and schematic be found for an Electron Kinetics eagle 7a power amp FWIW a good number of the semiconductors have been hard to find for decades now. So its a good thing they aren't damaged in this amp. Just get the filter caps replaced and you should be good. Not a bad idea to check the bias as well. | |
| Tube or solid state phono stage? I’m intrigued by the balanced inputs of the BAT. Does anyone know if that adds anything to the sound quality from a turntable input? @stewartgr I do! We've been making balanced tube preamps (with balanced tube phono sections) longer than anyone... | |
| Class A or Class D solid-state amplifiers (modern designs) @kawzx7 Your post doesn't seem to make sense. Perhaps you could clarify? BTW, one common misconception about class A vs class D is the first Watt, having to do with how well the amp behaves at the zero crossing. Both classes of operation do this e... | |
| Can an owner's manual and schematic be found for an Electron Kinetics eagle 7a power amp @gmosley Any Electron Energetic product is now old enough that the filter capacitors in the power supply are suspect and should be replaced. Failure to do so can lead to power transformer failure which would be a very hard and expensive part to f... | |
| ???Pre Amp Service??? @freediver If the preamp is over 20 years and its been sitting for 3 unused, I would have it checked out. Solid state equipment survives this a bit better than tubes due to the fact that electrolytic capacitors don't like heat (so they don't last ... | |
| Tube or solid state phono stage? I’m worried a tube phono stage may make the vinyl too warm sounding and not dynamic enough. @stewartgr Dynamics only comes from the signal. If it seems to come from the electronics, its because of distortion. Its much harder to build solid sta... | |
| Looking for 5AR4 rectifier tube most like solid state @boxsoft That preamp should put nearly a constant load on that rectifier. So Voltage sag really isn't a concern unless the rectifier is shot. If the power supply is properly designed (bypassed), the character of the rectifier will be very heard ... | |
| Diving into balanced @mtbiker29 There's a fair bit of misinformation here. Since we've been doing balanced lines longer than anyone else, perhaps I might set the record straight: 1) the advantages of balanced lines have nothing to do with length whether 6 inches or ... | |
| Should I get an SL-1200G @abill The tricky variable is the platter pad. Technics uses one that's terrible. If you want to hear what their machines are about you'll need a proper platter pad. The best I've heard so far is made by Oracle. Felt, leather, cork and rubber just... | |
| Pass XP-17 and Hana ML loading question This makes sense. Different designs do act differently when subjected to RFI. | |
| Pass XP-17 and Hana ML loading question @ssg308 1000 Ohms is so high a value it can't be affecting the cartridge at audio frequencies at all. So this has to be how the preamp is reacting to RFI. | |
| Pass XP-17 and Hana ML loading question @ssg308 I don't doubt you although I am a bit surprised. Others have reported Pass Labs phono sections as not needing 'loading' ('detuning' is a more accurate term) resistors. Simple decrease the load till its starts working... I'd start with 1000... | |
| Looking for a tube preamp that has xlr outputs. I sent an email to Schiit audio and asked if the Freya+ was AES48 compliant, they replied yes. See Freya review Sidebar 3: Measurements here.😎 Mike @ditusa I read the article you linked but it only mentions that the pin out of the XLR complies... | |
| Spatial Audio Raven Preamp The Raven has split windings on the output transformer so both RCA and XLR’s can be used at the same time (the RCA output uses one-half of the secondary winding). So feel free to use to use the RCA output to power the active subs. @lynn_olsen T... |
