Another thought.... IIRC the jungle IC in these was a Toshiba
TA8680. They were VERY high failure mostly for bad audio & AFT
problems. They were used in tons of brands & kept steaks on the
table for a few yrs. I did so many in Toshibas that I could do a complete
repair in abt 10 mn. The paperwork took longer !
Anyhows since I dont have the manual anymore cross the jungle IC to NTE
see if it comes out to NTE7010. If so its the same IC. The cross will
also pin out the IC so you can see what each pin is for.
BTW This IC shows some of the BS in parts prices. I could get them from
Toshiba for about $8. The same thing from Sharp parts was abt $25.
BTW #2 If you cut one open a jungle IC you will see its not an IC but a bunch of IC's in one pkg. Often each one has a separate VCC & GND.
Something to keep in mind.
