Condenser

Gary, I agree with these gentlemen that if the magneto condensers will fit in the stock location, they would probably be a better choice. (And they're cheaper than mine.)

Denny, that's very nice of you to steer me in that direction, and I really appreciate your advice. I guess I better ask someone here for a part number so I know exactly which one I'm looking for. Many Thanks Denny! GB

I cannot see why the cost would be a consideration with your "Trashcan" or a Vertex condenser. I consider them both "one and done". If a guy wants peace of mind buy a spare to draw dust! LOL The Tubman Trashcan is a thing of beauty to me.

From a post over on the Early V8 Forum


Many, perhaps most new condensers are simply poor quality.
NOS condensers are often defective due to age. A couple of years ago, I'd tested perhaps 50 NOS condensers and found just four as I recall that were still within spec.
I have had great experience with Hunt's Magneto condensers. The 32mfd is the best choice in my opinion. A bit pricey but hey, once and done..

The vertex magneto caps look to be home made and somewhat similar to the subject cap in the OPs first post. They plug the end with what appears to be an epoxy compound. I still use the Echlin brand but since they were bought out by Standard Motor Parts, I don't know if they are still reliable or not.

TCM/Bendix 1200 series aircraft mags have a large cap, or condenser if you will, that fastens as a carry though with a little diamond shaped bulkhead and two screws. Some of the 200 series caps are more conventional but they are smaller than the average automotive type. I don't know what the micro farad capacity is on them. They are expensive. Slick aircraft mags use a large screw in cap that is about as well suited as the TCM 1200 series caps. Too big and too expensive. The Vertex types are less expensive and likely just as good. Folks that make them one at a time generally use very good mylar insulation and good quality foil when fabricating those little jewels. They test each one too. That's why they are expensive.

And don’t all aircraft have two independent ignition systems? If any component on one system fails, the second system keeps the engine running?

Thanks Pete and Rotorwrench. I saw some used aircraft condensors on ebay. Mostly from Bendix mags. Apparently they get switched out at a certain number of hours use. Seem's the aviation world commonly refers to them as capacitors, but same thing. I think the 28 mf one on Pete's link would be what works for a mild street engine like most of us drive. I have not pulled the trigger on anything yet, but I know I want a good quality part.
