Fan model of HP Agilent E3644A?
« on: July 15, 2013, 03:52:47 pm »
I have repaired a E3644A with a problem to the circuit controlling fan speed (found a bad opamp).

I think during previous repair attempt they have replaced the fan with a wrong model because now, even with output off it is very noisier (actually noisier than my rigol 1052e)

Anyone know if the original fan for this power supply is the F6025E12B?
