Vinyl static ionizers who's used them?
@lewm  Industry uses ionizers extensively for electrostatic discharge (EDS) control - here is a very basic description - Technical Guide - STATIC REMOVERS (IONIZERS) (panasonic.biz). There are many compact bench top ionizers available such as AC... 
isonic CS6.1-PRO ultrasonic record cleaner
@drbond, There is no best.  Most any decent UT machine with the appropriate attention to the details can be made to yield excellent results. Are side firing transducers better than bottom firing, that depends on the tank volume.  Just keep in min... 
40khz vs 120khz or 40 plus 120khz US cleaning?
@george53, So long as it's a DC motor, and the power supply that is provided with it will state that, reducing voltage is a way to reduce motor speed.  Problems come up with high load/torque applications where the low voltage can draw a lot curre...

For vacuum-RCM always remember that YOU and the chemistry is what does a lot of the cleaning. The chemistry w/o good agitation is not going to do as much as it could. The vacuum-RCM rotating platter brush action is actually very slow. And while en...

Getting details from you is like pulling teeth.  If you are using the Audio Intelligent 3-step process, there is no need to change.  Since you are talking details, how much IPA and Triton X100 were you using?

If you optimize what you have I doubt you will get much benefit from adding the 120kHz UT unless your 40kHz is on the way out. Here are some suggestions for the hardware you have. With the VPI-RCM, preclean with Alconox Liquinox Amazon.com: Alcon... 
40khz vs 120khz or 40 plus 120khz US cleaning?
Without knowing the details of your current cleaning process, and what your goals are, it’s impossible for me to make any recommendation. Are you using any chemistry with your current UT? Are you intending to replace your 40kHz or use it with yo...

If you search the internet, you will see that 450W (~41W/L) is a pretty powerful unit.  If the heat-energy balance holds, the tank will heat from just the ultrasonics at about 1F/min.

Your spinner sounds like the VinylStack unit; its the only one I know that can spin that slow - 0.13 rpm. You can spin too slow. Depends on the tank power and temperature. I recently assisted someone who likely damaged a record, but he also allow ...

@flemke  Shapertek is a US company, and the model you list is 11L and total power with heaters is 850W.  Call them on the phone and ask them how much UT power is in the tank.  High Frequency Ultrasonic Cleaner XP-HF-450-11L-120KHz (sharpertek.com... 
40khz vs 120khz or 40 plus 120khz US cleaning?
@flemke, Here are some basic UT rules: 1.  Power needed to produce cavitation is inversely proportional to kHz.  So, lower kHz requires less power to produce cavitation. 2. Cavitation bubble size is inversely proportional to kHz.  So, lower kHz... 
Investigating if ultrasound is harming LPs
@terry9 , No, I did mean to say <60kHz.  Here are the basic UT rules: 1.  Power needed to produce cavitation is inversely proportional to kHz.  So, lower kHz requires less power to produce cavitation. 2. Cavitation bubble size is inversely p... 
What is the best way to clean Vinyl?
@odysseas_gr,  The difference between Tergitol 15-S-9 and Polysorbate 20 is mostly surface tension.  It's up to you if you want to want to play around with IPA.  If you do decide to mix in IPA, fix mix in the Polysorbate 20 then add the IPA or th... 
Lyra and OMA
The whole concept of arm effective mass and resonance is only a small part of the overall synergy between a cartridge and a tonearm.  This paper goes into the derivation of what effective mass means and how that relates to the cartridge compliance... 
What is the best way to clean Vinyl?
@odysseas_gr,  Yes, you can first rinse the Tergikleen with tap water and then immediately follow with DIW rinse and vacuum, but here is an alternative.  When using tap water, the key is not to allow it to dry. First, make sure you are using the...
