For there to be line whistle, which I guess there isn't, there has to be a negative voltage (-1) at Pin 5. The signal here comes from the line oscillator valve. This is V18.

This valve is a 6/30L2. If you haven't done so already, change C105. Other places to look are R110, R115, C107 and of course the valve itself. It might be worth giving the line hold control a clean, make sure it works OK and giving it a tweak.

Cheers,

Steve P.
