Thank you very much !!! :-)

M51725L seems to be another Sony replacement component for their own 
CX065B - none of seems to be available anumore.

Regarding NTE1300:

I agree that the mentioning of "8 TV Remote Control" is strange.

But the NTEs own datasheet on NTE1300 sheds some light over this and 
confirma that it is the right component:

Description:
The NTE1300 is a silicon monolithic integrated circuit in an 8–Lead SIP 
type package designed for use as a Frequency Servo Control System for 
tape recorders and VCRs.

Functions:
D Wave Shaping Circuit
D Sawtooth Wave Generator
D Comparator
D DC Amplifier
D Regulator

That's the one I'm going for

Thanks Martin - for leading me on the right track

Best regards Uffe :-)
