hp 5334A Frequency Counter 100MHz

Pick up this in junk yard for a low price and found inside all corrosive due to battery leakage!  After I do a cleaning and washing on the main PCB and replace all 6 pcs 100uF 15V cap with new Panasonic FC capacitors,  the set can work as it is.  Gone through performance check and all ok, self diagnostic also all OK, frequency can measure up to 105 MHz and level down to 35mVpp which is a bit better than spec.  Date code of part is mostly at year 1986, this this is a 30 years old hp equipment and is still working fine!  Made in USA.
