| The torroidal power transformers below are made on our specs. They have all the connections you will ever need for many different amplifiers, like multiple high voltage windings, power tube, pre tube and rectifier heater windings and taps for the bias voltage. They are very suitable for DIY, since they can be used in any project. These torriodal transformers have more windings than normal torriodal resulting in lower core saturation and much more easy and clean sound. They typically are twice or more as large as a normal commercial torriodal of the same power output. Also they have statical shielding, which is quite special with torroidal transformers. They are Class II (militairy), so can handle more heat and voltage peaks. They also are RoHS compatible, lead free soldered | |||||
