Just bought (through two different sources) what appears to be a first year SVT (says made in NJ on the back, no magnavox or selmer) with a warning about hearing damage. Recent retubing with 6550's. Also picked up a cab that has been re-upholstered but also appears to have the original CTS speakers and is from the very early years, possibly even '69. Would love to hear comments from bassists who use similar rigs. Thanks!
