Another Celestion Ditton 66 Renovation thread

Richard, one thing to remember is that many loudspeakers of this era were hand finalised by measurement when they left the factory to account for the differences in drive units. Therefore it is not uncommon to find different crossover compoents in the left and right speakers - I've seen this on more than one pair of Leaks!

This would account for the different capacitor values you've found but if you're matching up the drive units then don't worry - you can make both channels the same.

That makes sense, Adam. Thinking back, it would have been helpful if I had noted whether my buzzing/damaged MD500 was driven by the crossover with 24uf or the crossover with 30uf. Sadly I've swapped the drivers between cabinets several times over the years so have lost track of which originally belonged to which. Hypothetically, damage to the MD500 would be more likely to occur with 30uf than with 24uf, all else being equal, since a higher uf value would push the 500Hz crossover frequency lower, would it not?
