M58473 PLL in the Royce "Sardine can" setup


Does anyone know if you can do a "switch mod" to this pll or does it need a different xtal?

Can't find any good pages on this pll chip

Thanks in advance and Merry Christmas to everyone here!

You can mod it, but, if I remember correctly, the PLL board will only give you up to 27.575 or 27.595, not very many.

The owner is hoping to get 27.555, his 2000 bit the dust in a thunderstorm. Just trying to get his very old backup going for him. Does anyone have the mod to do it? Thanks again Timrim!
