Hi All,
I am hoping there are some experts here on the Grundig TK64 Reel to Reel
I have spent a lot of time restoring one, see video link

But after it was used for about 3 hours, i noticed it was quite hot, but perhaps normal. THEN THE MOTOR JUST SLOWED AND STOPPED !
The Motor wont start. The schematics dont show the color coding of the wires used, so i have taken photos. I guess the motor cap may have gone, but its impossible to get to (and there are two motor caps, in between the chassis and electronics, virtually impossible to access) it, so a cut and bypass is needed.
BUT i cant figure out the wiring to do this.. please see the voltages measured.
GRUNDIG TK64 is voltages at motor tag strip
0 AC
127 AC
133 AC
I tested a Grundig TK40, and measuring across the 3 pints, i got
119 AC
315 AC
285 AC
Any help to debug the motor not running appreciated and tips to cut and bypass the internal motor start caps greatly appreciated.
