Heads that don't need a speaker load

So if you don't need a cab with a given amp does this mean you can connect a cab rated below the minimum recommended ampedence.

Nooooo!

No cab means an very high/infinite impedance and so no current from the amp

Low impedances draw very high currents potentially damaging the amp.

The TH500 doesn't need a load - saw Dave from Aguilar discussing it a while back on Talkbass.

& +1 to Phil. Not a good idea to connect a cab below the minimum impedance...unless you like smoke.


[[Quick (related-ish) question - My TH500 is on the way from a fellow BC'r but I don't have a cab for it yet. I'll be using it with a variety of cabs until I can afford a pair of those DB112s :D

Obviously I can run it into 2 x 8ohm or 1 x 4ohm cab, but is there any way I can use it with a combo? It'd be great to still have the TH sound in any situation.]]

I think perhaps that has been copied and pasted from one of the Orange valve amp manuals. I've yet to see a modern solid state (or hybrid) amp that couldn't be run without a load.

I know, but what I mean is I think they copied it from the ad200b manual and pasted it into the OTB manual!
