glass bullet shape.  Under the "M"

                             21 (or is it Z1?  Probably Z1 looking 
closer.  Hard to tell for sure)
                             03
                             8648

Two of them measuring open in a Lambda (company, not Korg :-) ) power 
supply circuit.  Are these really not diodes perhaps but something that 
might normally be off scale on my 4v diode checker? -Bob
