[Milsurplus] BC-669: If You're Interested In the 669

[David Stinson]

If anyone is seriously interested in the BC-669, this
crystal set is a good accessory to have and a 
bargain at this price:

The crystals have large blanks and are easy to 
etch to frequency.  The brown ones often have
open electrodes but are easy to fix.

I don't know the man but he has 100% feedback
on hundreds of transactions.
