Primary Windings announces the introduction of vacuum impregnation for mains transformers

Fed up with hearing that mains transformer buzzing all the time, ruining your new amplifier you have just spent months building?
All our mains transformers are now vacuum impregnated. This means that they run almost silent and have better electrical insulation properties as well.
Try them, you are sure to be impressed
