Interesting very high frequency radio amplifier affiliated with an unknown Jet Propulsion Laboratory space probe, measuring 7″ x 4″ x 3″, with a JPL plaque on top: "Section 331, Communications Projects, Name: 140 Mc/s V.H.F. Amp. Ser. No. 1, Schem. 2-130345." The unit has ports labeled "J1 Input" and "J2 Output" on either end. In very good to fine condition, with overall tarnishing to the finish.
