[This is about measurement equipment, but looked like the most appropriate forum]

We have an Infiniium oscilloscope DSO80204B which is now obsolete and no technical support is available from Keysight. It was working fine and abruptly stopped working a few months ago. We have traced it down to a faulty power supply module(image at https://drive.google.com/open?id=0Bx-nrboXc1_HZUU0ajhTRUd5MEUyMXRZZkYtLUVmOVd6R2...). Is there any place where this or a similar power supply would be available? or can be repaired. We will take responsibility for installing it.
