Victor QL-Y77F motor speed unstable
I have a Victor QL-Y77F turntable that one day started to miss the speed lock.  Even when the motor is in stop mode, the platter still rotates a little bit (random actually) backwards.  When is in START mode (33 or45rpms) the speed randomly jumps from green to red and back, meaning from stable to unstable.
I tried to replace the Crystal and then the Hall generators but with no luck.  Actually without the service manual is pretty difficult.  Do you have any ideas what to do further?

TIA

Pioneer A109 erosito nem akar bekapcsolni
Jo estet mindenkinek!
Adott ez a Pioneer A109-es erosito, ami semmi eletjelet nem mutat. Azt gondoltam nem lesz nagy kunszt megjavitani - drotta valt vegtranzisztor ami vitt magaval egy biztositekot is....Nagyot csalodtam! Vegtranzisztorok mind jok, feszultsegek mind megvannak, de egy arva led sem eg...  Oda eljutottam, hogy a "proci" megkapja a maga 6v-os tapfeszet, de ennyi. Van egy4.19 MHz rezonator ami nem tudom el-e meg, de kivaltani csak kvarc-al tudnam. Elvileg a rezonatorban benne van a kvarc melle dukalo 2 kis kondi is. A kerdes az lenne, hogy ezt a rezonatort hellyettesiteni tudnam-e a kvarc+2kondi-val?
Elore is koszonom.
 
PIONEER XR-A550 HIFI TÁVIRÁNYÍTÓ PÓTLÁSA, HELYETTESÍTÉSE.

Sziasztok!

Szeretném pótolni ezt a távirányítót. Sajnos elveszett.
Típusa: CU-XR048
A távirányító képét csatoltam.
Ha valaki tudna segíteni benne azt nagyon megköszönném.Esetleg ha a helyettesítő típusát tudná megadni az is jó lenne.
Természetesen nem kívánom ingyen.
Üdv:
