SVT3 non-pro completely gone over, pots removed cleaned and reinstalled, switches cleaned, solder inspected and cleaned, new EQ sliders. Outputs removed, applied new heat sink compound and reinstalled. Tested 100% functional, no issues. Only diff between this and pro is this uses core power transformer whereas the pro uses a tyroidal power transformer making a non-pro somewhat heavier in weight. All controls, functions and outputs are the same. Weight 32lbs Shipping not included.
