But anyhoo, there can´t really be anything special with how the Wizards work with the TAE (or any other load) when compared to using a cab. Watts are watts, ohms are ohms. A load is a very basic thing.....
This is not correct.
The impedance curve of the load is critically important to proper functioning of the output stage of a tube amplifier.
There are some poorly designed load devices on the market that have dangerous impedance curves, with the impedance spiking up to hundreds of ohms at certain frequencies, usually in the lo frequency area. Use of a depth control at large volume will make this situation worse.
The fly-back voltage from this condition will destroy the OPT.
The ONLY load device I would use or recommend at this time is the Suhr stuff. YMMV....
If using the TAE, I would suggest do not use the resonance control set to any setting other than low.
