[Premium-Rx] [OT] Search for HP5328A Option 030 schematic

[Alberto di Bene]

Sorry for the OT message, but I bought recently at an hamfest
an HP5328A counter, with the 010, 011, 021, 030, 040 options
and need some help.

The counter works ok, only the prescaler (Channel C, option 030
up to 512 MHz) refuses to do its duty.

I asked to a friend who has the 5328A service manual, but he told
me that his manual does not have the C channel schematic in it.

Does anybody have that schematic ? I will gladly pay the copying and
shipping expenses.  I would like to try to fix that board.

Many thanks,
