I made an amazing find at the Electronics Flea Market yesterday!

Anyone know where I can get the rubber boots for the pen carosel in an HP7475a plotter? I have a couple that have dry rotted and can't find a source. (https://partstore.encompass.com/item/3220797/HP/07475-60038/)

Here is another picture of the whole set #HP9816, #HP7475A, hidden an #HP9122 and an #HP9134, the Bruël & Kjær 2034 and the #HP4277A LCZ meter.

The first plot of the #HP7475A after the #repair went very smoothly. Here is controlled by the #HP9816, plotting the impedance vs. frequency of a 4µF 400V polypropylene #capacitor (that shows a nice resonance at 300 kHz). https://www.youtube.com/watch?v=UvrfeoOsdLM

The 3D printed wheel seems to work perfectly! Source: https://www.thingiverse.com/thing:4696713 #HP7475A

Meh! This piece has become brittle and self destructed at the first attempt! I’ll try to 3D print a new one as apparently it’s a common issue. #HP7475A

I think it is a good occasion to test the #HP7475A plotter 🙂 I still have to clean it.

For all HP fans, a beautiful HP 9872C plotter from my collection in 4K as it draws the Columbia space shuttle.

Enjoy the sound 😍
