Saw mention of the Delco transistor ignition option in my 656 I&T manual. I don't remember mention of it in the operators manual. I was wondering about its lack of popularity and googled it. Seems moisture intrusion and heat were detrimental to it when used in the GM cars from the factory. Heat and water are 2 things a tractor gets a lot of--so likely even more problematic than in a car! also the germanium transistors used were not as good as today's electronic components.
This is not HEI, but an earlier attempt at high voltage ignition. It was stock in some cars around 64-70. Has anyone been around a tractor with the Delco transistor ignition? How long til it got thrown in the junk and replaced by a regular points distributor?

That is the unit I installed on a 656. No electronics in the distributor itself, still used points. Only one I have ever seen for that matter.

thanks for the conversation, pete.
it's neat to see what was state of the art but never caught on. Now electronic ignition is popular.
i also found a link to a build your own transistor ignition project if anyone is brave--it's much simpler than the amplifier system you installed and uses the original points as a trigger.
then again, pertronix has a warranty and could compensate for a worn distributor cam.

The only factory electronic ignition I am familiar with on IH gasoline tractors is a package IH offered. I installed one of them on a 656. It still used the original distributor and the points. It had a transistorized module and I don't even remember now if it used original ign coil or different one. It worked well as far as the points lasted forever as they carried such a tiny amount of current but I don't remember that it improved engine performace all that much. It did last though as it was still on tractor last time I saw it just a few years ago.

I found IH evidence for it in the CIH parts diagrams for the C-291 and C-200 engine. take a look then google Delcotronic and see what makes it tick...
although it wouldn't be for the 656 if only available on 291
