Ampeg V4B 2x10 1x15 question

Recently purchased an early 70s V4B and was wondering if it would be okay to plug in my current cab setup. I'd be running it into an ampeg 210av and an ampeg svt 115e. Would I set this thing at 4ohms or 8?

Will post pics when it arrives

That setup is 4 ohms total, if I recall the impedance of those cabs correctly. So set the amp to 4 ohms.

Two 8 ohm cabs (assuming they're in parallel, which they are in this case) = 4 ohm total load for the amp.
 
So, Ohm wise, with your amp set at 4 ohms, you should be fine.
I'm am however not so sure about the blend of a 115e with a 210AV, sound wise.
But then again, maybe it will sound great.

Yeah, the 15 was the result of my 210av not being able to match my drummer. I've thought about ditching it, and snagging another 210av, but I'm going to see how this sounds first.
