| Reel to reel If you are looking for new tape, Full Compass Systems is were I get mine.https://www.fullcompass.com/Not saying they stock it; I had to wait a month to get some reels of 1" tape. I suspect they have the 1/2" and 1/4" in stock but I've not checked. | |
| Class D amps History of audio:First we had electrodynamic speakers. They were expensive to build but they sounded better. As soon as it was practical, the industry moved to permanent magnets. It was not about sound, it was about the money.Then came the transit... | |
| The Audio Gods are tough but fair-Have you had the "Curse of the 300B" ? My listening level is never more than 65-70db in a room measuring 15’D x 25’W. That’s plenty loud for me 😊96dB is at the upper end of moderate efficiency. You might think its playing loud enough, but if you ran an amplifier that was making less h... | |
| Question About Audio Research Preamp Specs 1: If you own the AR pre, tell me the size (uF) of the output coupling cap, (it will be the big ones near each output) and what the poweramp input impedance is you want to use it with, and i’ll calculate at what low frequency it’s at -3db for ... | |
| Constrained layer damping tape on toroidal transformer? @ketchup I would like to know why you say not to use a stainless nut, though. I build a lot of stainless parts for race cars and for food and beverage and try not to use stainless nuts on stainless bolts due to galling, but that’s only if they ... | |
| Dual vs single sub The idea of 4 subs is the correct one. In case its not clear, the problem is standing waves and this is not easily corrected by room treatment if it can be treated at all.But its easy to treat with 4 subs. Just do what Duke mentions above. He's a ... | |
| Open Baffles with Subwoofers @bryantdrewWould Could the Tangband 8" full range driver be an option for your project?They are not expensive, have reasonable efficiency and bandwidth. | |
| Constrained layer damping tape on toroidal transformer? Getting rid of DC on the AC line with a DC blocker is the best option. Even a slight amount (less than 1/2 volt) can cause many toroid transformers to become noisy. DC blockers are not expensive.Most damping materials are also insulators. Transfor... | |
| The Audio Gods are tough but fair-Have you had the "Curse of the 300B" ? Question: would 300b amplifiers work with my ~93dB efficient JBL 4430 studio monitors? Or do I need something more efficient than that?Unless you are playing the speakers nearfield you either will need more power or more efficient speakers.Again,... | |
| Spectron Audio Out Of Business? why can’t someone just share the schematics? Is this the same Spectron Audio as http://www.spectronaudio.com?? | |
| Question About Audio Research Preamp Specs What does the "20K ohms minimum load" tell me?Exactly what it says. Most ARC preamps are not recommended for amps with anything less than 30K but this one is good to 20Kohms. Your amps though have a 10K input impedance, which essentially means th... | |
| The Audio Gods are tough but fair-Have you had the "Curse of the 300B" ? Here is another link you all may find interesting. Eddy's article covered a good deal of the basics, but one thing he really didn't go into is how the amplifier interacts with the loudspeaker. Since SETs run zero feedback for the most part, this i... | |
| Installation of new AC lines......best way to ground to avoid loops and noise Follow the electrical code of your local municipal area. ^^ This.@jsautterYou gotta get with the program and go balanced!But-If you are concerned about ground loops, the thing to do is make sure that the equipment you use has competent grounding s... | |
| Recommended Speaker List for Atma-Sphere OTL Amplifiers. How does Tannoy & atmasphere match up? Especially in the bass department......Very well is the short answer. | |
| Got My First Tubes ! What the heck do I do now!?!?! (Nube status) Fisher made pretty nice stuff but that was a long time ago. The power supply of the receiver employs things called filter capacitors (round cylinders near the rear of the receiver) that store energy from the power transformer. They are electro-che... |
