[sdiy] LM1303N

[synth at oldmail.charlielamm.com]

I just got a jar of about 30 of these, they look NOS, at the local surplus
place for $2 (along with a bunch of LM565s and some 2N3708's, all very NOS
looking). The jar had on it, hand written, "stereo preamp Lin IC".  So I
bought them.

I haven't been able to find much about these chips, except supposedly some
Kustom amps use them.

Does anyone know anything about them?  I couldn't find a data sheet for
the National part; NTE's 275 data sheet, which I think is their version of
this, is pretty sparse.  Anyone have a data sheet?  I couldn't find one on 
National's site.

Thanks...
