I actually use the 8 ohm with either one 16 ohm cab or 2. I just set my head on 8 and plug in either way. I had a 16 ohm for awhile, but sold it and got another 8 ohm. It sounds better to me.
Yep 8 ohms is what you want. I have one in stock if you want it, make you a good deal on it too.carlygtr56":9c0ea said:

Most everything you'll come across as "one size fits all" is an 8 ohm load that you can mismatch to 4 or 16 ohm. You're SOL for 2 ohm stuff though.
And stuff like the Ultimate Attenuator is a 32 ohm load that gets fed into a SS power amp.
Indeed, the powerbrake is build around a transformer switchable between 8 and 16 ohm.kannibul":3e2da said:

Wow..I never realized the HP was so flexible...sounds like a single step mis-match in either direction on the 8Ohm works.
It seems a bit confusing though...do I set the amp always to 8Ohms (the Hotplate load) or the speaker load? Seems like two different ways are given above but they are talking about both 8Ohm and 16Ohm HP...so hard to decipher conclusively.

shit i didnt know you could mismatch them?!
i always thought you had to match them all the time
16ohm head>16ohm hot plate>16 ohm cab...etc.
I have a 16ohm hot plate but always wanted to use it with a stack but I thought I had to buy a 8ohm hotplate for use with 2 16ohm cabs.

Here's the deal, when you mismatch with an attenuator you use the impedance that is the lower of the impedances following it.
i.e. 8 ohm HP and 4 ohm load (2 8 ohm cabs) you'd use the 4 ohm setting on the amp, or
8 ohm HP and 16 ohm load you'd use the 8 ohm setting on the amp.
on an Vox AC30 the you'd have to swap the transformer wire to the 8 ohm tap to use it with an 8 ohm attenuator.
To keep in mind there are some amp builders that will void your warranty when using an attenuator. I believe Roccaforte and Fuchs are 2 of them.
Which is due to mercury Magnetics voiding their warranty to the amp builders I'm told.
That said I believe an amp should be able to run happily full tilt boogie with or without an attenuator.
Then there are guys like Mesa, Bogner, VHT, Soldano that actually suggest out product.
And guys like Marshall, Aiken, Komet, Dr.Z , Trainwreck, us (THD) that have you use their attenuator.
That applies not just the Hot Plate, but any attenuator or mismtach for that matter.JKD":ec59a said:

Ok so this will work?
8ohm setting on a marshall 2203 to 16 ohm hot plate to 2 different 16 ohm 4x12's?
