As I promised, I prepared the test in the content "Making a unique record cleaner".
I would like to add that the washing equipment I made is not a precise equipment designed by an engineer, as it was built from what happened to be in my hands!
(But if a manufacturer sponsors me with one, I will accept it! contact information below!)
For washing, I used the basic washing liquid, which I explained in this section: How did I make a unique vacuum plate washer?

To prepare the test, I chose a piece of music that contains details that are quiet enough to hear the elements that are undesirable from the sound point of view.
A good quality headphone is definitely recommended for listening to the test!
The test recordings contained the following components.
Pickup: SHURE M7 5-6S (spherical needle, which is not the best choice, as this design is less sensitive to dirt accumulated deep in the groove)
Turntable: Technics SL-1500 Mk1 (1976)
Amplifier: Technics SU-C800UM2/SE-A900SM2
Digital recorder: Tascam DR 05
Recording parameters: 24bit/96kHZ
Format: WAV
Camera: Huawei P30Pro
DIY camera slide
