I spoke with a fellow who has a print set for the board, he indicated that
there are no diodes on the board at all. There are, however, quite a few
bypass caps shown on the schematic. My glass devices are all in parallel,
each associated to a particular, IC, and are grounded on the other lead.

I will have to remove an intact one to check resistance and determine what
they are.

Thanks for the reply,

Kevin
