Technical Data

I will give you just a few technical data from an original Partridge output transformer for a DR103. These datas can be different in a range of +/- 10 %, but it will show, that this was a very high quality output transformer for guitar-amplification. As soon as possible, I will publish the technical data for a Marshall 100 Watt output transformer for comparing.

How we are mesuaring the different values, just read this.
