If I look at the schematic provided by AndiGer the transistor 094 is replaced with a 2N3904
If I look at old posts or the Jaques Laporte documentation the 094 is replaced with a PN3646

According to the HP Master XRef, an 1854-0094 transistor crosses over to an ON Semi MPS3646.

Coincidentally, Sphere has an 1854-0094 in stock.
