Please help identify this transistor, and a possible substitution. It's from a built-in phono/USB preamp from an Austrian manufactured turntable. Thanks!

@Piranha was a bit faster than me, but we came to the same result. :grinning_face:

Yes, you are right, the typo you mentioned is definitely one, and should be read a LE50ABZ-AP instead of LE33ABZ-AP. Thanks for this tip!

Thanks @Piranha & @Peter BENSCH,

Funny. I was going through that data sheet and was momentarily confused by the same typo. But...I put the LE33 on a 9v led tester and voilá, 3.3v! Out of circuit, the le33 outputs 3.36vdc. In circuit, 0.01V.

Thank you both for helping me resolve this.

Cheers,

James
