Good to have the confirmation that it fitted and congratulations of the repair. |

I got two more for repair 1 x 53132A 1 x 53131A Both were free but they are in horrible condition. One turns on with errors (But weak VFD), the other does not do anything Missing windows, missing switch buttons Broken and corroded BNC connectors. Seems like a nice winter job. On one of them the little rubber (?) distance foot is melted away to gunk. May be the instrument was in a bad environment. |

Quite the winter project indeed. One of my 53132A's had the rubber melt, it was a puddle on the lower chassis, no sign of it was left on the PCB itself. Looks like your unit was stored on its side and it ran down the PCB which is uglier and likely no fun to clean up at all. I have a spare display window but it is likely easier for you to get a few from Keysight directly along with whatever other parts you need. |

HP's (electrostatic printer for 9100 series calculators) and Tektronix's formulation for printer platen rollers (1503 TDR) are particularly good at it... (Hint... look at 3M cold shrink tubing for rebuilding those) I had to clean and replace the snot glob in my 53132A and it lived a cushy indoor life. |

Ok, the first one is fully cleaned up and ready to be assembled again. It was so much sticky, nasty dirt everywhere, it took several deep cycle bath tubs in pure alcohol, to take it all off. Repair so far: 1. One power resistor exchanged in the power supply 2. All 5 BNC connectors replaced to new 3. New VFD installed Seems to work again, the new VFD is nice a bright. |
