   The 2 or 3 letters - number - possible letter format for transistors
is the European
labelling scheme.

    From my copy of Tower's,

ADY26 PNP Germanium. Case T036 with lead-out L13. Vcb max 80V, Vce max
40V,
Veb max 40V, Ic max 25A, Tj max 90C, Ptot 100WH, F1min 100KHz, Hfe
15MN,
Hfe bias 25A.

Use - audio, high current, general purpose.
Manufacturer - Mullard.
European equivalent ADZ12
US Equivalent 2N1100.

That's all I can tell you about the beast,

        Dave.
