Did you need to use some kind of divider for the local oscillator frequency to feed the PLL?
Thanks Sinus!

There's an MB501L between the VCO and the PLL chip (divide by 64) as the MC145152 will only go up to 20 MHz or so.

Finally got round to putting a rig together - my first time. Everything seems to be working ok so far.

Good guesses. It was an old twin CD recorder. The sections cut out the front are ideal as ventilation for the amp heatsink, and to access the phono socket. Got some ferrite rings to fit and some tidying up, but works well.

Looking good Barry06! :)

If you are into a bit of fabrication? You could make your own front panel, Maybe re-route the LEDs for a true custom design?

But yeh! Excellent work!
I am as stupid as I look! :|
