See a few older postings covering this here in s.e. Faults I had to repair myself in a some TDS5xx: power supply (dead SMPS), and a lot of failed caps on the boards. hth, Andreas |

How to determine this or get the gov't part number for the manual,I don't know. I believe the USAF PMEL cal labs,if they do still exist,would have the data.If you could hunt down the phone number for a PMEL lab,then they might help. -- Jim Yanik jyanik at kua.net |
