        Wellllll... I don't recall how to connect them to a model 33, but the
'Radio Amateur's Handbook' should have a diagram that shows how to hook
them up to at least get tones out of them.

        FYI, the 35Y3D was the standard pad in use in most 25xx series desk and
wall phones for many years.

        Aha! This is the same as the Y3D model, but with extra muting contacts for
use with speakerphones.

        Those are hard to find. If you end up not using it, may I talk you out of
it? I'll happily pay shipping (and, say, $5.00 extra?)
