Technical Data Output Transfomer

Enclose you are finding a lot of picture of a nearly orignal, but very used, HIWATT DR103, build in 1974, with four inputs and famous PRARTIDGE transformers. This amplifier cames in for a complete restauration. Important notes can be find directly to the pictures. In the near future, we will add several pictures, especially from our output and power-transformers for this type and how we are building them. Up to this point, just enjoy the pictures. For enlarging, click on them.
