This is a round 3-pin socket for many different transistors, but common Germanium transistors which use this are 2n404, 2n1305, 2n1307, 2n1309, and many, many more. These also fit some silicon transistors like , which is used in the GuitarPCB FxxxBxxx circuit.


Note that the circuit board must be laid out for a TO-5 transistor or TO-39 package with .2 inch spacing between the non-adjacent pins. Please refer to datasheet for compatibility before ordering.


Available in an economical 5-pack or 10-pack.
