umbes täpselt ~52-3 miskit kinnitust sellel service manualist ei suutnud leida
kas selle 2sd947f 40v 2a 5w võib asendada Darlington; 45V; 4A; 40W BD676A-CDI midagi lähimat ei suutnud leida va hiina kloon. Konded on plaatidel nagunii kõik sam young'i kirjadega

Kui toide on +-53V, siis tagant ette lugedes kõik kolm transipaari mis ühes õlas, peaks vähemalt 30% suuremat pinget taluma. Nii oli see vanasti, võibolla uuelajal on teisiti. Ma otsiks transid, mis vähemalt 80V taluksid. Sorry kui offtopic, sest skeemi ei süvenenud, pakun kogemuslikult.
