luxman k-15 - rec mute problem

[wmincy]

Dear all,

I have an old second hand Luxman cassette deck model K-15.
Even if 20 more years had past, this machine still sounds incredibly good. It was well built with it's almost 12kg weight.

I have a problem with the rec mute function.
It doesn't work, and I tracked down where the problem could be.
In fact, looking on the pcb, I found a missing connection at the rec mute signal pin, seems the wire was cut and I can't figure out where must this signal be connected to.

If you got this cassette deck can you please help me out with this?
Kindly appreciate!!
thanks

Mincy
