Ditto.What is a shoebox radio?
Ditto.
LM2902 has open collector outputs, and cannot drive LEDs as you have them connected.
I have no other comments, because I have no idea what you are trying to do.
A Google search for shoebox radio yielded multiple hits for Barenaked Ladies.
Shoeboxes are the same in most of the USA. However, in Pennsylvania, everyone wears wooden shoes, so the boxes may be more substantial.A few observations.
In the UK a "shoe box" is a cheap flimsy cardboard box which holds new shoes in the shoe shop.
People have been known to keep all sorts of things in them, their treasured possessions, money (so that the taxman does not see it), whatever.
However the concept of building a radio into such a thing is mind boggling.
While you may have the greatest affection for this radio, I cant help but think that you are polishing a turd.

Hey don't feel bad. I built a radio in cat food cans. I'm sure a few guys around here remember it. But it sounds like you are using a pre-made radio. So here's a grand idea. Why not make the radio. It could be very cheap and you won't have to rip out the tape deck. There are some ICs that have complete FM receivers in them. Don't ask about mine as it was all discreet components but the dern thing works great. I swear it out performs my Icom 745.
That would be an excellent idea except, the radio I'm using now is more powerful than anything I could possibly make right now. But that is an excellent idea, like I said, the project will never be finished, it will only continue to get more complicated, and more advanced. Any suggestions on what kind I should use? (the speakers are rated for 8 watts) I know I've brought this IC up a couple times, but the LM3886 would probably be where I would have to stop working on it.

If the input to the voltage regulator is 24V but its output is only 12V then it is throwing away half the input power as heat.
The Sanyo audio power amp has an output power of almost nothing. Why not use a modern high power amplifier IC?
