Cheap ultrasonic cleaner

This is indeed the same as the Lyman "Turbosonic 2500" which retails for much more! "Turbosonic" indeed...... where on earth do they get those names from? I've nothing to compare it to but mine seems to work as long as I keep the buzzer (it doesn't seem particularly "ultrasonic" to me) going for more than five minutes.

Yes, I'm currently using some of their brass cleaner, EPB25R, in my U/S cleaner from the 'Bay.. works a treat..but it looks like its discontinued, as a search on their site can't find EPB25R, but its still available on the 'Bay...

The one originally linked to has dropped to £39.99 delivered next day. I really couldn't resist at that price and will spend the weekend cleaning bike parts (bigger ones I will clean the old fashioned way with elbow grease)

The buzz sound is because the ultrasonic exitation is pulsed - the ultraconic bit of course you can't hear.

Ah, I see. Must be very short pulses of ultrasonic then!

Mine sounds like 50 or 100 pulses per second. This probably reduces the heat build up in the transducer and drive electronics cos they're doing less work

The loud buzz is usually because the Ultrasound driver fire at about 25Khz which itself is silent, but the vibration it creates in the metal tank results in a lot of harmonic resonance - visible as ripples on the surface of the water.
If you look at the edges of the tank you'll likely find a dense rubbery seal which helps to dampen the harmonics.
Larger machines are still unpleasant to be around though. Sadly the really quiet machines are incredibly expensive as they operate at far higher frequencies.
