I have a late 40s early 50s Sun Dist machine that I purchased in the 1970s the strobe is getting weak and will only flash at higher RPMs, every thing else works as it should. Suggestions for repair.
I have a Sun 680 that the strobe was not working and I got a capacitor and diode kit from Paramount and that fixed it. http://paramountd.com/index.html
suggest that you take a look at the u-tube video by "Opera", very interesting modifications. Dead nuts accurate.l've posted this info before, no one seemed interested, here's the link to one of his videos, https://youtu.be/W7rXdZVCz1Q

Paramount had the parts to get mine working. A good distributor machine is so nice to dial in the points and check vacuum advance/adjust advance springs.
