I've modded quite a few amps for 6 M and I remove half the turns from the original choke. This reduces the inductance by a factor 4 and wo; /archives//html/Amps/2013-07/msg00036.html (8,122 bytes)

Inductance is proportional to aprox no of turns squared with a ferrite core. 1/2 squared is 1/4. If you were to keep the length the same (ie d; /archives//html/Amps/2013-07/msg00037.html (7,963 bytes)
