Agilent 53132A Counter Repair (FIXED and Upgraded)

The main PCB of my 53132A does not have connectors mounted for the blue coax wires. Also, the tension converter for the display is not on a transformer based design on a daughter board, it is based on a capacitor/diode ladder and is placed on the main PCB. The melting rubber for is not a melted gray goo, it is black in pristine condition.

Can you show a picture of this?
How old is this 53132A of yours?

All my 53131A and 53132A have the daughter board for making the VFD voltage.

I don't know when it was manufactured as it was bought used. I got it cheap with handle and bumpers missing. Unexpectedly it arrived with option 010, squeaky clean inside and outside, intact rubber foot on PCB backside, bright VFD, etc. Could have been worse.  :-+    Bought NOS handle and bumpers on eBay...

The main PCB has a date code of week 30 2008 and the latest component date code I have found is week 24 2008.

One picture showing 38V converter. Need more pictures?

Very nice!
My counters are all older and have the extra board.
I will have a look out for a newer model.
HighVoltage:
Yesterday I calibrated all my "old" counters against my HP GPS based 10 MHz reference and had them run over night to see the drift.

Here is the result in the picture.
Without analyzing the numbers, it appears that they are very stable after 24h.
They all have the option 010 installed.
