Hello,
I recently purchased an old pair of Janszen Z-600 speakers. One of the
speaker's electrostatic tweeter sections is not working. Upon opening
up the cabinet I found that a capacitor and another part were broken
away from the power supply board. The part I cannot identify is
labeled:

RECTICON CORP.
CONSHOHOCKEN, PA.
S 6350 G6

Any idea what this is? A didode or rectifier? Any idea how I can find
a replacement? I can't simply solder this one back into place because
it's lead has broken off right up against the body of the part. The
part is about 2 inches long and about 1/4" in diameter. Thanks for any
information.
