s400 regulator questions
hi. im pretty new to the group so please excuse me if this has been asked before.
has anyone fitted a reg to their s400 and what were their experiences with the results. which one did you use.
im not sure if the s400 will benefit hugely from one as its power seems pretty stable mostly
but being new to hft all advice is welcome
