Green Rhino IC pic...

A Green Rhino is being sold on eBay right now (all proceeds going towards the Tsunami victims too), and it has a closeup of the PCB:

Surprisingly, the IC isn't the usual oh-so-mojo JRC4558D, but a National LF353N.  If you look closely to the buffer transistor on the right, you can make out the characters "N2" ...so I suppose they're metal can 2n2222s.

Interesting!

Humm, I think I see a 4 as in 2N24??

You've got better eyes than me!  In that case, it could be a 2n2484:

metal can, general purpose silicon transistor.

Check out the tantalum caps and carbon film resistors.  I thought they had to be polyester film (made from polyester clipped from a shirt worn by SRV), with 0.0000001% metal film resistors.

Ooops, that was covered in the mojo thread

Assuming they want the charity. None of that makes any since to me. Great job and effort!!
