| A Worthwhile Untrasonic Cleaner Anovak,I received the Tergitol 15-S-9 and have worked out a good manual cleaning process. Manual clean with a brush, and then two rinses, first with tap water to remove cleaner, and then rinse with distilled water from a spray bottle, overall, us... | |
| Cartridge loading Bydlo,That article was modeling the mechanical resonances as an equivalent electrical circuit. I was trying to show that the mechanical resonances were more complex than I originally thought, and if the cartridge goes into physical resonance (whi... | |
| Cartridge loading All,Re-reading my response above, I failed to address the actual question. So, did some more research and came upon the site, http://pspatialaudio.com/index_help.htm which has a wealth of historical data, with detailed info, lots of calculations... | |
| 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... |
