Re: Chinese no brand ultrasonic cleaner
Can you post a pic of the whole unit? Sorry, I am just curious as I have one too. However mine only blew the fuse inside the socket once. Got mine now for like 4 years and still going strong.

Re: flourescent ballast resistance
Finding a 9w cfl ballast shouldn’t be a problem as these are very common. Only thing is, you gotta be damn near on the ball, otherwise too much or too little (wattage mismatch) will damage that lamp....
