PLL chip source needed...

[NightRunner]

Hi all,

I have here an old Yamaha RX-300U "Natural Sound" stereo receiver I've
grown rather partial to, and this afternoon I found it to be
completely dead in all functions and display but the amplifiers are
still functioning. My best guess on such short notice is that the PLL
controller has died, and was wondering if anyone might know a source
for this part.

It is a 42 pin DIP package and has the following markings:

YAMAHA XB919AO
PLL CONTROLLER
3214 8F2

I'm also investigating the power supply but would think that if that
was at fault the amps wouldn't turn on. Could be a low voltage
condition though I suppose.

Thanks for any help!!
