Hi andjur78,
I'm lost. What is the locator number for that part? All I saw were single TO-92 parts. 2SC1681, 2SA841 types are used as the original parts. 60V, 50 mA, 200mW, hFE 450 ish. This is a low noise part. 2SC1775A and 2SA872A are good subs. Do not waste your time with ECG or NTE parts. The cross reference book is useless, don't use it.

You can use almost anything to substitute to see if that's the problem and get the correct part later.
