My Madamp G2 worked flawless during many years but recently I was playing and it suddenly stopped (no sound, no glowing tubes,..). Turned out the fuse blew (infinite resistance, blackened). I ordered five new fuses, put one in today, turned the amp on and.. nothing. I checked the fuse and it had broken down also (infinite resistance but not blackened).
I then decided to look for short-circuits inside but found nothing so far. There's only one strange thing: the resistance of the primary (black wires)on the transformer shows 8,5 kohm, secondary red 250 ohm and secondary blue 1,2 ohm. The primary doesn't match with the readings from MAD:

Hi,
I've just checked my G2 PTs, the resistance should be like this:
black = about 127 Ohm
blue = about 0,8 Ohm
red = about 205 Ohm"
Question: is my transformer broken?
Greetz,
