Default Old Sony Walkman Question: Cause of Flutter?

Inertia of the flywheel. Can't fix it AFAIK. That's why CD players have the
delayed audio system.

I never noticed any perceptible distortion with cassette walkmans, perhaps
the belt is worn and slipping?

Depends on how much you shake or twist them! When Wal-Mart sell them for $5
it's hard to get keen on fixing them.

Flutter is caused by:
1. Rotten rubber drive belt (might look fine, isn't). Replace

2. Bad pinch-roller bearing. Lubricate or replace.

3. Bad capstan & flywheel bearing. Lubricat or replace the whole
thing...these are not normally replacable (staked to the chassis or molded-in).
