Hello uF is a voltage holding capacity, it is just a store in this application. if the circuit say's 1000uF and you use a 2200uF it will not care, but you must use the same 25v not lower.

APBERG, thanks very much, but the zip file I can not open it and I can not read, could you send me mormale?
I wanted to tell you that on my pcb and marked capacitor 2200 uf 25 volts on the base of you posted and a capacitor 1000 uf, I have to change my 2200? Thanks from the heart

what is diffrence base if u change 1000uf to 2200uf roccocoin

Carl please, just a quicky question, the optimum coil inductance for the Surf PI is.............? 300uH lower/higher Thank you. Kenny444

What kind of caps are all these square yellow caps. I've never encountered them in parts stores here.

Hi Bernd,

Photo's of my board. Sorry they are not from the best angle but it is a real pain to remove the board from the housing, but should be clear enough for you to see. I wouldn't worry about the component body types you want to use - as you can see, mine is made from whatever parts were in my junk box and it works fine!

Regards, Jim.
