40khz vs 120khz or 40 plus 120khz US cleaning?

Sharpertek said 450 for Ultrasonic and 400 for the heaters.

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.  

I have to wonder if this would be a worthwhile investment being that I already have a 40khz unit?

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 your 40kHz?

What are the details of your current 40kHz, tank size and power?

Do you clean used records or just new records?

How do manage your current bath - do you filter, do you monitor with a TDS meter, how often do you replace the bath?

The purpose of these questions is to 1st determine if there is opportunity to improve what you currently have before considering something new.

Edit - One more question.  How much effort do you apply to keep your stylus clean?  Or, does your stylus routinely pick up detritus that needs to be cleaned/removed?

1) Clean LP on VPI 16.5 to get any major junk off.

2) Run 3 LP's at a time in Vevor 40khz tank with splash of 91% alcohol and small amount of Tritan x-100.

3) Rinse off on VPI and let air dry before placing back in sleeve.

The tank I use now:

Vevor PS-60A which is supposed to be 360w US,400w heater, and 15l.

If adding the 120khz cleaning after the 40khz would make much of a difference is my question?
