Sun Distributor Tester Finished

Well... It's finally done. And sold. I think it went to a good home, but I'm a bit bummed about only having it completed for a very short time before selling it. I guess that's just how it goes.

Since my blog posts about this tester show up at the top of the list when searching for Sun MDT-50 information on Google, I figure I should show the machine all completed.

Here it is:

The rolling cart has been repainted, and a new decal applied

Mostly original paint on the tester units and drive unit. Original top mat saved and cleaned up. 

 Tach/dwell unit re-powered with a adjustable buck regulators run from the Sun 6V DCpower supply, replacing the old wet cell batteries. 

Original manual, scroll tune-up charts, and cool vintage Sun box full of adapters.


  1. You may not even monitor this site anymore as your last post is from 2018 but I just recently started a Facebook page called "vintage sun service equipment". I would love to have you and your knowledge about these machines on there.
