Hello !!
my english is poor, sorry.
i'm watching about capacitors, in the Cornwall they are all in 250 Volts, but with different values ; 25 µF for the biggest to 1,75µF for the smallest. Seven capacitors.
But can we change these values ? I have some difficulties to find the EXACT VALUES !!! so i will ask to Francis Ibre, the boss......
Here you can see a great test :

I try on one Cornwall and see after if it's good or not.
