    I have two WM-190, one with a split wheel and one with the flat cable connecting the head halfway ripped, but both in excellent cosmetic condition. I put the both together and put in a new belt and all went well so far. Now, when the motor is running there is a quite high pitched noise in the output. I tried to touch the board on several places, wiggled whatever I could and then replaced the whole board (from the second one I had one ready). The noise is still there. It changes though when I touch the "tape type switch".

    Anyone any ideas where I could continue looking (or guiding me to a thread which deals with this problem)?

    Thanks!

    Hi bub, thank you very much for your help! Since I'm not very familiar with their shape (I've soldered some Eurorack modules with parts like this before): It's the round "barrel type" ones with the black plastic bases (quite rectangular with two "cut off" edges, right? I count eleven pieces. Could that be?

    Same here, beautiful and very compact model. But it will be a lot of work to fix it... :(

    I just finished the smd soldering on one of them - and although I'm an absolute beginner at smd soldering everything went smoothly and it took me only about two hours. So: courage! If I can do it everybody can... :)
