Default Wad hd83

Hi there,
I have been using a HD83 for a long time now with a pair of Sennheiser HD600's.
With the HD83 output TX's set at 300 ohms.
My Question is does anyone have the info how to change the impedance.

As I have bitten the bullet and bought a new pair of cans the Quad ERA-1 with the impedance of 20 Ohms.

The means to do this will be in the build instructions. I am away from home at present and donít have access to the archive, but I return tomorrow evening, so PM me your email address and Iíll respond over the weekend.

If its the WAD it involves a lot of soldering and if its WD it is changed by dip switches, let Greg know what it is. Bob
