I got some beat up unit of aiwa px10 (same as 101 and px700) it was untested and i haven’t had any power source to test it at first. Meanwhile when i waited for battery case i swapped to new belt. This unit was never opened before had a paper stickers on pcb. When i received pack i finally tested and appears that red light, light up for a second and than fades away. I thought maybe i should recap whole unit i managed to replace almost every cap except these 2 47uf on right side of remote jack plug. Now the unit works and rotate cassette in ffw and rev mode but when it plays there is a huge problem. It plays for a second in high speed and than stops. I have no idea why it works that way so i'm thinking maybe somebody can help me with it. https://imgur.com/TknZrEj
