It seems impossible to open the black chassis on which are mounted. Monday I'll call an expert tech.. I hope and pray :lol:

Tomorrow i'll check the transformer..looking at the amp from the front, is the right transformer or the left transformer ?

Seriously ? usually do the valves broke ? e.d. all the valves suddendly stop or it's possible that only one valve stops and the other continues to work ?

As i said , i use a Voltage-current stabilizer so it's impossible for the amp to take a V-A jump. However i checked the main fuse and the tube fuse and they are perfect...

Hello , The last month i played in my home with spider valve mk II hd100 and after playing at very moderetely volumes as usual i cut power from it and i covered it with a bed sheet. A few day ago i power on it ,take a few second to heating valves with standby on, but all the valves did not work ! I always use a current-voltage stabilizer so it is impossibile for it to take some current-voltage jump and during this month never have touched it , so it's impossibile to take account of physical damage. All the valve doesn't not work at all, very strange. The amplifier hardware works very fine, all the lights are on , but the valves are not. I use it infrequently and at minimum volume, so although i buyed it 3 years and half ago it's strange that all the valves stopped to work suddendly. The last time i've played it there was a great sound, no oscillation in volume , great basses and dynamics. Please help me ..
