This is the crystal pack from a HW rig - 100 or 101 - not sure which.
But is just the SB series crystal pack soldered on a board. They
will work just fine in an SB rig - desolder and plug them in. Standard
pin HC6/U holders, soldered on a board. Look to be in good condition
(I realize looks mean little in crystals), but cannot really test them.
As they say on TV, 'money back of not delighted'
