ON Semiconductor / Fairchild Quality General Purpose, Power, Switching diodes. 20 pcs per lot.
Good sub for obsolete MV-12 & MV-13 (tie two in series), 1S2473 (Sansui), 1S2076, 1S1588, 1S2472 (Marantz), 1S1555 (Yamahas), [ VD1212, VD1221 (tie two in series) ]. Consider replacing all VD1212 due to the high failure rate.

Two 1N4148's in series will measure about 1.2V @ 1mA or so. Dual diodes are usually used as a voltage reference.
