What's the difference between tube Watts and Solid State watts in a guitar Amp?
I know that a tube amp with 10 or 15 watts Can Drive a Cabinet that is Rated for a minimum wattage of much higher than that of the amplifier. But solid state can't necessarily do this. What is the difference between tube and solid state Watt Amps, and How Big of a cabinet can a Small 15 watt amp drive?
A watt is a watt is a watt...period. Here's the formula for calculating Power:
P = E * I
where:
P = power in watts
E = EMF in Volts
I = Current in Amperes
There's no Variable for "tube" or "solid state".
Now Most folks will agree that when you Turn a tube amp up it will Sound louder than a solid state amp of the same wattage. This has to do with how a tube Handles a signal vs a transistor when they get to the limit of their operating Range. A transistor will Clip the signal abruptly, and most folks don't percieve that as a "Good" sound.
A tube on the Other Hand will Start compressing the signal as you increase it's drive Level. By doing that, the average levels of the signal are higher, and we percieve that as louder.
It's basically the same thing that Radio Stations do to their audio (and now mastering engineers) to Make the signal Stand Out.
Now, the question of "how big of a cabinet...". Well, I suppose you could Hook up a cabinet that's rated for 1000 watts to Your amp, and al Long as the impedances are matched it would make noise. And that's True of tube or solid state (again...a watt is a watt).
Don't get too Hung up on wattage numbers on Speaker Cabinets. What really impacts how loud a speaker System can get is it's efficiency. In other words, how well does it turn Electrical energy into acoustic energy.
Very High wattage speakers are usually pretty ineffecient compared to lower wattage ones. So, it's entirely possible to hook your amp up to a cabinet rated for 50 watts, and it's louder than the 1000 watt cabinet.
You usually see the "minimum recommended wattage" Spec on high fidelity speakers (because they Trade efficiency for accuracy). I don't believe I've ever Seen that on a guitar cabinet.
As long as you're Not mismatching impedances, feel Free to experiment.
Good luck.
Ken
