Kevin Don't forget that is a germanium transistor. Reads in both directions on a meter, if I recall it should be about a 10:1 ratio. Don't know if you can read them on a DMM. You may have to figure out the circuit and take a guess what the other one is. Its likely a Ge type as well. Al G Al's TV-Electronics Pembroke Ont.
