Mul hakkab tekkima mulje, et kunagi selle mudeli parts list-i (spetsifikaati) trükkiides on tehtud trükiviga (või oli see päris algne versioon), selle alusel on ostetud ja sisse pandud q103 positsiooni 2SD-d.

Hiljem (kui töökindluse tõstmiseks ilmselt) need diood-zener ahelad lisati, siis kirjutati Q103 tööd tegev transistor parts-listides 2SC-ks nagu nad ilmselt on. Sinu pill on ilmselt mingi üleminekuvariant, kus detailid on vanast laopartiist, kuid skeemilahendus juba osaliselt uuemast.

Sinu asemel kasuraksin ma uuemates skeemides kasutatud lahendust s.t. mitte-darlingtoni Q103-na.
