| How to improve power supply? I've use Sorbothane, in a number of applications. A great product. The bolt can contact the transformer, but needs to be isolated from the chassis(or vice versa). Nyloc nuts and flat washers are good for maintaining the position of your transforme... | |
| How to improve power supply? Keep in mind, if using MuMetal sheet; If it has to be bent(to any great degree), annealing in a hydrogen atmosphere is recommended, to restore the grain structure/permeability. MuMetal foil is also available, if you can arrange a way to surround t... | |
| How to improve power supply? Try a couple sheets of Sorbothane, with the cord between. Be certain that the bolt(s), holding the x-former, remain(s) free floating(isolated from the chassis) as well. Good info: (http://www.sorbothane.com/standard_product_guide11.php) | |
| How Things Change My greatest regrets have been at Noon, when I reread something I'd posted at 03:00(brain death, defined). | |
| What makes Telefunken tubes sound better? Generally speaking; the monetary value that people place on items, is a pretty fair indicator of how good they might be(You can fool some of the people, all of the time and all of the people, some of the time, but- you can't fool all of the people... | |
| What makes Telefunken tubes sound better? @Geoffkait- It's interesting how broadly a topic can get off course. Back to your conversation: My comments were restricted to small signal, nine pin miniatures. All my favorite octals originate from the 40's and are military designated, especiall... | |
| What makes Telefunken tubes sound better? @Mr J- The author of that article would have made Julian Hirsch very proud. I'm certain, if he had reviewed tube equipment; he wouldn't have heard much difference either. The sonic differences between various iterations and year of manufacture, wi... | |
| What makes Telefunken tubes sound better? Actually; some of the best tubes were manufactured for, "Post Germany" in the 1950's -60's. ie: The CCa is a special low noise, low microphonic, long-life E88CC/6922. Philips had similar designations for the Dutch Post, some tubes that were select... | |
| How Things Change Another way of looking at it: It was patently obvious(providing they could see) to the earliest Aeronautical Engineers, that Bumblebees could fly. A problem existed, however, in that early Science could not provide an explanation as to how or why,... | |
| What makes Telefunken tubes sound better? I might mention, as I have elsewhere; the EAT tubes are the closest anyone has come, in recent years, to the quality of the earlier products. But then the OP mentioned cost! (http://www.musicdirect.com/c-673-vacuum-tubes.aspx) | |
| What makes Telefunken tubes sound better? The Germans have been absolutely anal, with regards to materials, quality and engineering excellence, for a great many decades. The notion that someone else's products(new or old) could exceed their standards is laughable. I've tried a number of o... | |
| How to improve power supply? YES, Mr P: That silence reveals the truth of the saying, "You don't know what you've got, 'til it's gone!" | |
| How to improve power supply? Like many other electronic components; regulators generate noise. A number of ways to address that noise have been discussed and tried, by hobbyists and companies. ie: (http://www.edn.com/electronics-blogs/the-practicing-instrumentation-engineer/4... | |
| FYI: VPI HW-19 motors If you don't already use them; the SAMA and SDS also make major contributions to the performance of the HW-19. | |
| How to improve power supply? If your power supply does have regulators, replace them with Bellesons, which are much quieter(http://belleson.com/download/Superpower_datasheet.pdf). Replace the rectifiers, or bridge, with with either HEXFREDs or Schottky diodes. Parts Connexion... |
