 So until further information is forthcoming **we might ballpark speed controls on PSW reducing power to ~50% of normal and MSW to ~60% of normal**. But another Amazon reviewer((again, can't link)) says: So until further information is forthcoming **we might ballpark speed controls on PSW reducing power to ~50% of normal and MSW to ~60% of normal**.

 >> ...there is a hidden adjustment potentiometer inside for minimum power setting. Wall dimmer switches have these as well. I was able to adjust it, but I’m waiting for my tachometer to get it where it needs to be. By the sound of the motor, I can tell it will go down enough. They really should disclose this adjustment in the instructions… Note: The hidden adjustment is soldered onto the top side of the PCB inside but you need to use a small flathead screwdriver to adjust it from the back after removing the back cover. >> ...there is a hidden adjustment potentiometer inside for minimum power setting.

-See [[https://www.youtube.com/watch?v=-ilWK_VVEzc&t=710s|this video]] to see the pot adjusted.+See [[https://www.youtube.com/watch?v=-ilWK_VVEzc&t=710s|this video]] to see the pot adjusted. After adjustment secessus was able to hold 33% of rated power stably;  any further adjustment caused the circuit to drop out
