Ultrasonic Record Cleaner 40 v 80 v 120 kHz

Well, thanks again everyone, all great info. 

I should mention that I did purchase the Gem Dandy hydraulic cleaning machine. It is inexpensive and at least according to George Merril, it works well, as good as US. 

I was also considering the CS6.1 Pro. I figured after hydraulically washing 10 records, I would give them a second US cleaning, rinse and then spin dry. But based on the comments and a review by Fremer, it seems that iSonic is not really an US machine. 

I am starting to think the best option for US is a basic Vevor $200 cleaner. The unit has 180W of power. After US cleaning, I can use the Merril for a 2nd cleaning and rinse.  

Had an Audiodesk rcm  the year it came out. After about 100 records, the pump broke and it could not be sent back for repair. So I received a discount (not very much) on a new  improved Audio Desk. When that pump broke, I was utterly disgusted having spent about $7,500 on the two machines. I switched to the current KL Audio with which I am very satisfied. Bonus--if it breaks, I can have it repaired in the U.S. 

@jwr159, 

Be advised that inexpensive UT tanks like the Vevor can be very noisy; enough to drive you out of the room or wear hearing protection.  Also, you will want to buy new power supply that can slow down the motor such as  Amazon.com: Belker 36W 3V 4.5V 5V 6V 7.5V 9V 12V Adjustable Voltage Universal AC/DC Adapter Power Supply for Household Electronics Security Camera Router LED Strip Light Keyboard Tablet - 3A 3000mA Max. : Electronics.  

You can add a filter that can extend the bath life for not too much money - Amazon.com: iSonic 1 Micron in-Water Filter for P4875II+MVR, P4875II-4T-NH+MVR or P4875-NH+MVR : Industrial & Scientific.  You will have to adapt it to the Vevor. 

If you can keep the bath clean, you then monitor the bath with a TDS meter.  They are available for <$15 but they are generally not very accurate at low levels with this being the lowest accurate unit I have found - Amazon.com: HM Digital 716160 COM-100 Waterproof Professional Series Combo Meter, 7", White/Purple : Industrial & Scientific.  You refresh the bath when it reads 5-10 ppm.

Or, pre-clean with Merril unit and then final clean/dry with the HG HumminGuru Ultrasonic Vinyl Record Cleaner | RCM | Recording Cleaning Machine; see the manual here HumminGuru Owner's Manual.  The HG only uses 400-ml of DIW and you just replace about every 6- records.  FYI, the general consensus is that the new more expensive HG-Nova adds some convenience, but it cleans no better.    

Good Luck,

Even the pricey US cleaners can be noisy. I use the silencer box for the Klaudio cleaner and it’s very effective.
