Hmm, jos nuo T-kaupan Ampeg-elementit ovat varaosia SVT 8x10 rantasaunaan niin sitten ne taitavat olla impedanssiltaan 32 ohmia, lukaisepa alla oleva Ampegin kotisivuilta löytynyt tekstinpätkä:
 
The SVT speaker cabinet is introduced in 1969 using an infinite baffle (totally sealed) design that houses eight 10 inch speakers in four compartments. Each compartment holds a pair of speakers and is completely sealed from the rest of the cabinet. The speakers each have a 32 ohm impedance and the eight speakers are wired in parallel to yield a total impedance of 4 ohms. Removable dollies are included with the cabinets. By 1977, the cabinet no longer has the removeable dollies but has a pair of fixed wheels to tilt the cabinet back while navigating the amp using the new "towel bar." The CTS speakers give way to Eminence drivers around 1972. In 1980, Ampeg designers install new speakers which give the cabinet a power handling rating of 350 watts. This allows the player to use one cabinet instead of two with an SVT head.
