while it took longer to sort out than i'd have liked, ec confirmed the proper method so i wouldn't blow up the 2nd amp, & they sent me free of charge a brand-new transformer, so i could repair the 1st. they also sent me a box of proper fuses.
these amps are being used vertically bi-amped, in place of an aw75 & an aw100 i previously was using, horizontally bi-amped. until i can afford the care-n-feeding of some mondo tube amps (or completely change gears & go for horns & flea-power amps), i have no interest in changing my amplification. electrocompaniet is great equipment, imo. while their service may be slower than one may hope for, i tend to give 'em the benefit of doubt - they are a relatively tiny company, competing w/big players. i like 'em, i like the product.
