    I have purchased a 1971 Ampeg SVT, but I'm having problems using it with my current amp, which is a Peavey firebass 700. Any way to make the two compatible??? My old Sunn amp works well so I assume it is a ohm issue...

    Ya that wont work since your amp only goes to 8 ohms and your cab is 4 ohms you would destroy your amp.

    Because you would be putting to much of a load on it.

    2 4ohm cabs=2 ohms
    2 8 ohm cabs=4 ohms
    2 16 ohm cabs= 8 ohms

    You might want to refer to the OHMS FAQ thread.

    I presume that your "1971 Ampeg SVT" is an 8x10 cabinet not an amplifier...true?

    Looking at the online manual, the Peavey Firebass 700 can go down to 2 ohms. Peaveys are known for driving low impedance loads well... Where did you get the 8 ohm limitation from (looking at the manual, the marking on the back of the amp even says 2 ohms)?
