Hi,
can someone help me to figure out what transistors this are ? They are part of an inputstage - I have tried to search on smd code lookup websites but I couldn't find them. Case is SOT-223 or SOT-89
Could it be
PZTA92T1G and PZTA42T1G ?
I have seen them extensively used in a Dan D'agostino amp.

Yes, you are correct, from the Onsemi datasheets (page 1)
P1D = PZTA42
P2D = PZTA92
RRT and RSB
R/R = Assembly Location
R/S = Year
T/B = Work Week
P1D = PZTA42
