Tube Integrated Sub hook up

[uw69]

So I'm thinking about getting started into a tube integrated amp. Almost all of the ones I've looked at have no sub out or line level out for a sub. They all seem to have both 8 ohm and 4 ohm speaker posts.

Whats the trick to hook up a sub to these tube integrated's?

You can run the speaker-level outs of the integrated amp to your sub first, and then from the sub to your speakers. That's probably the easiest way.
