Raising the While Flag on 604 Project

I believe the serial number stickers tell the difference: Serial numbers beginning with a printed A are for OKC (believe it or not), and those beginning with a printed K are Anaheim.

Gary can correct me if my memory is wrong on this.

I've been wondering how to tell these apart too, but my 604-8k's don't have an A or a K on the serial number sticker, only 02191. Are there any other tell tale signs, like magnet sizes?

The date code will also tell you - it will be something like 8234 - whcih means 1982, week 34.

If I remember right, Altec moved to OKC around 1984, so anything before that would be the original design, but beware - they had lots of QC problems then...

The other is the size of the magnet - it's huge.

OK, both mine are labeled 239792. Is it possible that 8k's were made as early as 79?
Thanks,
