U medjuvremenu izvršena AC modifikacija po ideju sa linka ispod :

http://tweakaudio.com/EVS-2/Gustard_X20_Mods.html

 

Here are some AC power mods that are simply mind blowing:

1. Bypass the fuse with copper foil (or use audiophile fuse if this scares you)....now I even bypass the fuse holder for even better sound.
2. Remove the hardware from the transformers and raise them off the chassis using doubled up carboard donuts.  You can then use nylon nuts and bolts without much tension to hold them in place.
3. Twist all AC wires tightly (both into and out of both tranformers and between front and back boards).  You have to remove the heatshrink tubing from the wire before you can twist them.
4. Remove the input AC filter.
5. Remove the 110/220 volt selector switch.
6. Remove 5 AC connectors inside the unit.  You have to desolder and remove the circuit board mounted to the AC inlet.
7. Remove the power switch.

If you do all 7 things above then you will have both transformers hardwired directly to the AC inlet.  Black wires from transformers go to neutral and white go to hot for 120V.  If you have 240 then use black to neutral and red to hot.  Tape off end of unused wire. To turn on the unit, you plug it in.  To turn it off, you unplug it.  There is no reason to turn it off....it does not use much electricity.  The sound is now incredible.

Primetno je osetno poboljšanje dinamike posle ovih izmena.

Razlika izmedju Lampija i Gustarda je ozbiljno smanjena .
