[Amps] fil. chokes

[c s]

        I have wound several experimental filament chokes for an SB200 
and All Are somewhat larger in value than the original. The last one I 
just made is 48.5 uh. Is there any problem in using a larger choke ?? 
The original chokes are around 10 uh If I remember right and are 
considered marginal on 80 and 40 mtrs. What , if anything should I be 
concerned with here. I used some .5 in x 4.0 in . ferrite rods , 61 
material.!!! Any comments ??
