There is only one manual as far as I know and it is "Operating
and Service Manual".
My manual says "This manual applies directly to HP 5370B's having
serial number prefix 2904". It's manual partno 05370-90031, October
The first couple of changes are:
1. (5370B below 2904A02706)
Change A22U22 from 1820-3699 to 1820-1399 to IC-FF ECL/10KH
D-M/S POS EDGE-TRIG COM.
2. (5370B below 2904A02391)
Remove conections from
U19A pins 6 and 8
U19B pins 14 and 16
U20A pins 6 and 8
U20B pins 14 and 16
U23B pins 14 and 16
Let me know if there is anything I can help you with.
