Here's my new old Philips PM 5771 Pulse Generator. Fresh from Ebay.
I was lucky because the device is fundamentally functional. Unfortunately, the signals do not always look good, which is due to the switches and potentiometers that need to be cleaned. In addition, the Elkos seem pretty drained, even if the power supply still works. Capacity and ESR is OK, but Vloss is very high.
The optical condition is OK, no damage. Inside, the device looks untouched and full of dust.
Here are some pictures of the structure. As usual at the time of manufacture, the frame is made of solid cast aluminum profiles so you can repair the unit very well. Everything is already arranged accessible.
After a short test run, I find that it is even below the 2.5ns rise time something, I could measure 2ns at about 110 MHz. Above all, problems make the pot for the delay setting. Producing a clean signal when the delay is on is dire. It works, but not clean in all positions.
I will restore the device gradually. Need some advice about cleaning the pots. These are fully enclosed and high quality.
