One of my amps is an SVT-CL. I am about to buy a 3rd cabinet but my current cabs are a Berg HT322 (4 Ohm) and a TL606 (non original 4 ohm speaker). I built the TL606 in 1984 and realize I might get better performance with a new brandy new Eminence 3015 driver instead of the Carvin unit. New speaker arrived and I JUST realized that the SVT does not have an 8 ohm tap This amp is a super clean US model that I intend to keep forever. Does the Kappalite get returned?
