We couldnt have an exact copy of the older design even if we wanted to with key parts being discontinued in the older designs.

For SBS Designs amplifiers, key parts are made to order & Spec for SBS Designs amplifiers exclusively.

FYI the internal layout has been used by my Engineer / Designer for 20 yrs and we will keep using it!

Hope that answers your questions
