Exactly ! If there was 10A passing through that choke I could understand the use of that wire . According to Jeff's mentor , Dr Halijak :
'A choke must have some internal resistance and its non-standard figure of merit is the ratio R over L. The best choke is the one with the smallest figure of merit and the best power supply has the least series resistance. It is not too difficult to obtain R over L = 10 but one can easily obtain R over L = 30 or more. The latter should be avoided but the ongoing shows that in a way it is unavoidable.'
Those chokes have a F.O.M of 7.8/0.32=24.75 which is on the borderline between low-fi and audio junk . A slight contradiction but according to Jeff and his rather small band of choke-choppers , it is a worthwhile mod...
