RE: Maximizing Magnet Efficiency of Coil Speakers and Toroidal Transformers




Alan,

I simply cut lengths of UltraPerm slightly longer than the straight run of each part of the ground wire to allow for corners. The UltraPerm 80 can be folded over once to create a trench but that's it! So it's an imperfect world but the payoff in tone makes messing around all worth it.

Here's a picture from 2014 after which I improved the UltraPerm installation and added many tweaks. Regrettably just messed up my amplifier following my first major re-installation mistake (due to haste in a local professional's store where a loose connection had been resoddered after disassembly). So have again been removing all tweaks prior to shipping it back to the manufacturer who finds them offensive and I cannot now take a more recent shot.
