| Cartridge loading atmasphere,The article I referenced was only to address the affect of inductors. When you say, RFI, are you talking radio frequency interference, or in general, electro-magnetic interference (EMI)? EMI encompasses conducted emissions (CE) , cond... | |
| Cartridge loading Atmasphere,No arguments of the electrical-mechanical fundamentals, but the aspect is not well doucumented for cartridges, and therefore, the nay-sayer(s) will debate. However, that being said, this document shows how the phono-preamp design can a... | |
| Cartridge loading All,This artcle http://www.gammaelectronics.xyz/s_1987-8_cartridge-tweak.html, makes the following statement "The importance of the resistive load across the output of cartridges was reported by J. Peter Moncrieff in 1980.[2] He found that a lower... | |
| Frustrated with Vinly A problem with many new records is that they have a poor sleeve, often only paper and many have a lot static, and a carbon brush will not remove the charge. Other than maybe the Gruv Guard or Zerostat, wet cleaning will get rid of the static char... | |
| Frustrated with Vinly Jay, etal,A lot of the problem, especially this time of year with cold temps and low humidty is static charge, which will make the newest album sound like rice krispy's. There is Gruv Guard that uses traditional ammonium salts for anti-static. J... | |
| A Worthwhile Untrasonic Cleaner Anovak,The data on Tergitol shows that one of its benefits is improved dissolution rate, i.e. how quickly does it dissolve. Temperature and agitation improves the dissolution rate, but only up to point. When the water is close to the cloud point... | |
| A Worthwhile Untrasonic Cleaner 25ml should be more than enough. If you notice any rinse problems, reduce to 20ml or even 15ml. Using too much is worse than using not enough.Hepastat 256 is a Bactericidal, used to disenfect surfaces. However, it has at 0.5 ounces per gallon,... | |
| A Worthwhile Untrasonic Cleaner Anovak,One last item, the concentration to use for the Tergitol 15-S-9 is 0.1% to max of 0.5%. This product requires about 3 times less concentration than Triton X100. The technical detail is something called the Critical Miscelle Concentration ... | |
| A Worthwhile Untrasonic Cleaner Anovak,I need to make a correction here. Essentially, Tergitol 15-S-9 is a more environmentally friendly (and by DOW data should be more effective) alternative to Triton X100 which because of having components that can mimic estrogen, are toxic t... | |
| A Worthwhile Untrasonic Cleaner Anovak,I did a little more research and there are a number of theads that talk to the 15-S-3 and 15-S-9 mixture, some referencing that this is what the Canadian Archivists use, and some saying that the mixture equals 15-S-7. Surfactants are clas... | |
| A Worthwhile Untrasonic Cleaner Anovak,First, sorry my calc for ounces of 15-S-9 per gal is incorrect, its about 1 ounce per gal. I was in a hurry and rushing out and could not remember if a gal was 64 or 128 ounces, but it would about 30 ml for a gal that is 3.78 liters.The IPA... | |
| A Worthwhile Untrasonic Cleaner Tergitol 15-S-3 is not water soluble, it is intended for oils. Dow has a nice pdf handout with tables on all the Non-Ionic-Surfactants/Detergents, and you can read on the differences. For the Tergitol, use 0.5 to 1.0% solution concentration, whi... | |
| A Worthwhile Untrasonic Cleaner All,As a suggestion, substitute Tergitol 15-S-9 for the Triton X100. You can buy this at Talas, one pint is $21.75. The 15-S-9 is very similar to the 15-S-7 that the Smithsonian uses for shellac record cleaning, except it has a higher cloud point... | |
| A Worthwhile Untrasonic Cleaner SAFETY ALERT!!!Hepatstat 256 in its concentrated form is dangerous, its deadly. Read the Material Safety Data Sheet (MSDS), and other Warning labels. This is an Industrial product, and unless you have experience with proper Personal Protective E... | |
| phono preamp for the ortofon 2m bronze Kully,Good to hear it all worked out. For a linear power source with R-core transformer, check out Wyred 4 Sound`s, PS-1 modular linear power supply. The version with one high current (3A) module which would be required for the rPhono, is only $... |
