Hmm. Not going to be a pernicious vendor on here of all places Berger.
But - if you have a condenser problem as opposed to summat else, a dodgy coil or whatever, then those pipes and the mag have to come off, so not a 20 minute job I'm afraid
With a K2F/K1F/KVF (or any rotating coil mag with the condenser at the opposite end from the contact breaker) there is the possibility of just cutting a 'link' wire that traverses the bobbin from condenser live side to points. So you don't have to strip the armature itself, which neeeds some tools and/or resourcefulness (I know you have both in truckloads if you can be bothered!) - but in all cases the armature itself has to come out.
Sometimes even with K series mags whose condensers have already been replaced once, the low tension tail wires off the coil can't be got at easily due to their being buried in resin. Delicate is the word in those cases. 99% of the time it can be done, but with great care. If the parts are original, it's a lot easier to disconnect the condenser - but only worth doing if the HT winding remains good. Which has to be a bit of a Question, owing to the possibility of insulation failure or an internal break in the secondary winding. There are some basic tests you can do on that - continuity cold and hot for start, but to be sure of things you need a coil tester of some sort. The Lucas workshop instructions contain info on that which is as good today as it ever was, and explains how.
As to whether the cb end 'EasyCap' capacitors work, then I'd say they do. About 20,000 out there now in 7 different versions, and although I only have 5 of them on my own magneto bikes, I've never replaced one and I don't bother carrying spare ones on my keyring any more. I've probably fitted a thousand or so by now on mags of all sorts from the very dawn of time to Joe Hunt wasted spark units for track use, but I've never really counted! Famous last words of course, as nothing's for ever, but so far so good. The one on my A10 went on before we ever launched the product, so best part of 10 years, and same for one of my AMC twins. But, they had rewound coils, new sliprings etc etc at the same time, so I knew I was starting on a level playing field. Since then I've stuffed them on another AMC twin and 2 Norton engines of my own, also on loads of flywheel magnetos, battery and coil systems, etc, you name it. Rotating coil magnetos are the most delicate jobs to do because of their inherent design . . . but the idea is that if it ever has to be done again, it's a screwdriver and 2 minutes (no swept backs to remove), no mag to take off, and take apart, replace and re-time. We started by saying the things should be regarded as a 'service item' like the condensers that came with sets of points for old cars, but the reality is I haven't changed my own, and don't try to flog the things to anyone else on a 'just because' basis. I don't know what the service life is, and may not live long enough to find out frankly, but absent cack-handed abuse it way exceeeds the 2 years they're warranted for. Fingers Crossed.
BUT, doesn't offer you a super-quick fix I am very sorry to say.
