Philips PM3217
Taken from Mod note:OSC167.
Alternative transistor types for Amplifier Unit PCB, because transistor BF338 is obsolete, component changes:
V1417 and V1423 into BF470 (from BFT45)
V1418 and V1426 into BF469 (from BF338)
R1437 and R1439 into 100E
C1407 into 1.8pf.
For replacement in older instruments, BF338 remains available.

So I suggest that what you have is correct.

Other Mod notes relate to new Y output amplifiers. From both the /02 version and again for the /05 version, the brown look version.
A revised power suppply from /04 version.
No changes apparent for the X output amplifier.
