I am Mark Lord, as you can see from my profile. Eutronix is maczrool/Stu, who posted above.
Stu handles nearly all repairs and upgrades these days, whereas I am simply the repair of last resort guy. If Stu can't fix it, then I will.
But I only take on the dirty, broken, complicated repairs, not routine stuff. Except in cases of Canadian residents, for whom I'll take on anything empeg related, to save them cross-border shipping hassles.
