Here's the nitty gritty right here.
   

For the P.S the 17.5v from the receiver is dropped first by a resistor then thru a 78L08v reg. 

The other two transistors are to isolate the 17.5v stereo lamp circuit from blowing out the led driver in the 8v chip.
 First is a pnp which is turn on by the led drive which then turns on a npn to pull down the actual lamp ground for the stereo ind.

Only other thing of note is the cap for the vco. It calls for a polystyrene one. I think it's supposed to be more stable than most other types.

The reason I chose this IC chip was ebay for about 13 bucks. They were part of a module board for car stereo.  the boxes say panasonic on them.  
I am sure there are obsolete by now. There are still some chips by them selves on ebay.
And I do have a magical link to a pdf data sheet I found. It's to somewhere in japan.   It took me almost an hour to find it.
And yes it works good. It's always nice when something you build works.
