Big trouble with Pre Phono 2

[LSfarzo]

I will be out of my home for a week, due to work. I'll be back on the end of jab. Then I will change the valves with a brand new triplet for testing purposes, to be sure they work (or at least they should !).
Now I am using 3 x 12aX7 Electro Harmonix, since about 2003,

Second, will double check every pin in case of accidental touching, but i
would consider this pretty unlikely.. anyway better do not leave nothing checked.

Thanks everybody for your precious support !!!
