This is very valuable experience as the whole DIY processes were done by myself starting from data gathering, buying components, assembling, testing...
There is still low level of noise when hearing close to the speckers (with low frequency hum sound).
Did you read "MUKA" article, he use AC voltmeter to measure the noise instead of ears.
Try to get this machine and tunning the VR to get the lowest value.
Good luck
