i had a 30 yrs. old belt in my grundig beat boy 120 walkman. changed the belt, but there is still a little bit wow and flutter ... azimuth screw was near screwing out, so sound was damped... i corrected it... but i`m not shure, if this could come from a disjustaged head... i cleaned already with isoprop ... the only thing i can do, is, to give some oil to the motor... atm i`m checking the tips here .... happy to find that...

is the pinch roller ok ?

it seems .. its clean and it works .. how can i see, if it doesnt work proper ?

i meant has the roller a good contact with the flywheel or out of shape can the tape run with the cassette out so you can see .

i`ll check it ... busy atm. thx for answering so fast .. .

it seems everything ok ... i can even shake the player and it doesn`t really wobble.. but the squaere belt is twistet between two wheels, but only one edge further ...
