Re: Why don't guitar amps use Toroidal Transformers Toriodal Power Transformers are not widely used because: They are expensive.     There are some minor differences compared to conventional xfmrs, but for power as oppossed to audio output, these differences are negligable. These differences include differing saturation characteristics versus using laminations.     The primary benefit of toriodal xfmrs are:     1. Size: they tend to be smaller for a given power level.     2. They are self sheilding, meaning that their magnetic field is contained within the powdered iron core of the toroid and have minimal flux lines flowing outside the toriod itself. For that reason, they provide for quiter operation because they do not induce AC voltages into surrounding wiring.     In sum, toriodal power transformers are superior in most respects to conventional transformers.       LFO
