| Acoustic Foam Panels - Blu Tack ??? If you have sheet rock walls, medium length common pins will work fine for smaller panels, say up to 2' x 2'. Be sure the head of the pin is secure (many plastic tips will come off rather easily), and that you try to distribute the weight evenly u... | |
| Power Supply Whine, Need Audiophile Help Actually, Bob was quite correct in his response. ALL computer (read "switch-mode") power supplies have some degree of high-frequency whine. Read up on the design priciples behind SMPS and you'll discover why they make that awful high-frequncy whin... | |
| task lighting suggestions My criteria for a suitable lamp was that it must be flexible in positioning, have no transformer (or any other sort of noise-producing quality, either physical or induced over the power line), and preferably NOT clamp to an existing rack or stand.... | |
| LP12 - identifying Cirkus bearing The Cirkus bearing is flanged out at a 45 degree angle as it mates to the bottom of the subchassis. The original bearing is not. I think I have a picture of both kicking around somewhere. The color of the bearing well is not relevant. You might al... | |
| How do you clean your RCA female inside ? If you have an electronics wholesaler in your area (NOT the Shack), see if they carry GC Electronics products. They make a "cotton applicator" (a Q-tip) with a pointy head that is absolutely perfect for female RCA jacks. If you go to the GC Electr... | |
| Ungrounding an Amp--Any Danger? Defeating a three prong power cable with a "ground lifter" etc., is not only dangerous, it defeats the UL listing (Underwriter Labs is an independant body which tests electrical devices for safety under extreme conditions), and will invalidate ANY... | |
| Transformer noise including Powervar I built the second link Jea48 mentions in his post, which is essentially the same as the link I posted. I kept it simple and used a piece of perfboard mounted on nylon standoffs. Everything can be configured point to point, and takes up no more th... | |
| Transformer noise including Powervar Try this:http://diyparadise.com/dablok.htmlto remove that pesky DC from your mains supply. Remember, only a few mV of DC can make toroids hum like there's no tomorrow. I used this same basic design when I built my DIY Armegeddon-clone power supply... | |
| Morph the Cat deheaded I'll side with 4yanx here - Morph is fine sounding LP - mostly analog, but one which has obviously seen ProTools. I think one of the nice aspects of this vinyl pressing is that it demonstrates how FAR digital has come in the past 20 years. I would... | |
| Online for a variety of acoustic room treatments? Try the Auralex stuff - the absorbtion and diffusion solutions I've tried from them seem to work quite well. I got mine from AV Alive, which was the cheapest on the net. They also do custom fabric panels (more pricey) in a wide variety of colors a... | |
| Ping Pong Projector Beam Unfortunately, you can't use an ordinary mirror for such an application - the image will double due to the first reflection bouncing off the surface of the glass, and the second reflection bouncing off the rear of the glass (the painted/silvered s... | |
| Cleaning tube sockets I use the little gum stimulator/anti-periodontal disease brushes from Oral-B that can be found at any drugstore. They work quite nicely for the pupose, and have a robust wire that can be bent into nearly any position. They do tend to shed bristles... | |
| soundproof a door Tough one without replacing the entire door with something considerably more substantial. Maybe sliding glass or at least the same door in a solid core format?? If not, you might consider filling the door cavity with low expansion foam to at least... | |
| High mass turntable owners -- What Stand? Salectric, Thanks for the responses. I ask, because in the near future I hope to acquire a new high-mass deck, and will need to adapt the stand I currently use which is a single shelf unit. I had my stand custom made by a welder, and it is essenti... | |
| High mass turntable owners -- What Stand? Salectric,Assuming a high-mass, high rigidity stand sitting on a poured concrete basement floor, what would be your material choice(s) for top mounting platform? Please discuss advantages and disadvantages of the materials cited. Many thanks,-Richard |
