Any competent mechanic with a multimeter can test the coil. There are specs that can be easily checked.
Next, you can check the ignitor by swapping in one from another distributor. Accord and prelude parts are interchangeable here. The differences between the distributors are here:
The housings between F and H are different. Also, the shaft has differences.
The coils are different, but I believe they only have changed part numbers because of the mounting locations. They are essentially the same.
Some are internal, some are external. The right cap has to be chosen for that style.
That being said, you could convert the distributor yourself, especially if you have a couple extra dizzys laying around like I do. You need a good philips screwdriver, some snap ring pliers, a clean bench, and some patience. The internals of the distributors were not made to be replaced piece by piece. You could use A SHOT DISTRIBUTOR and not touch your good one. All of the internals are traded out in the swap anyway.
Your other choice is to just add an internal coil to your existing distributor and hack up the wiring a bit. That's no fun, so I would opt against it.
