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,...

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...

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...

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...

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...

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 $... 
phono preamp for the ortofon 2m bronze
kully560,The Arcam at 40db will multiple the input signal 100:1, so a nominal input of 5.5 mv will output at 0.55 volts.  The nominal signal ended output from a cd player per redbook is 2 volts.  So, the Arcam will need more volume.  I did a quick... 
phono preamp for the ortofon 2m bronze
kully560,My version of the 2M BLACK is circa 2016, which would coincide with the version that lowbeats.de tested, and my preamp gain is only 6db.  I suspect your version of the 2M Bronze is more recent, and Ortofon may have corrected the output vo... 
phono preamp for the ortofon 2m bronze
kully560,If you check www.lowbeats.dem, they tested the 2M ortofon and they yielded 10 mv.  I ran the rPhono at 30db with the 2M black and plenty of gain with the volume conrol at a good level, the 2/3rds range.  Otherwise, if you dig deeper into ... 
phono preamp for the ortofon 2m bronze
I recently purchased the ARCAM rPhono and use it with an Ortofon 2M black.  The HiFi+ review is what I experienced.  The build quality and range of adjustability without having to go into the unit is quite remarable for the price, especially since...

I am probably crazy for jumping into this conversation, but boldly going in; there is a lot conversation with a lot of experience on this subject, but from a engineering perspective, actual analysis can be pretty light, and the accuracy of vendor ... 
VPI's new "Vanquish" Ultra High-End turntable is a STUNNER!
I have a TNT, but it has been significantly modified, I machined and added a 0.25" thick MIC-6 AL constrained layer plate to the bottom, and added a 2nd armboard courtesy of a delrin Avenger armboard and it sounds great, but the cost to manufactur...
