I was just lollygagging around today and browsing through the manual of my Phoenix Gold Octane amp. To my surprise nowhere on the manual or the web page does Phoenix Gold claim they use MOSFET trasistors. Furthermore, after checking through Phoenix Gold's higher end lines there is no statements about the use of MOSFET technology.

Now I have done my research on the forum and there doesn't seem to be any threads which are specifically about MOSFET technology. Therefore I have a couple questions for the experts:

1. Is MOSFET simply a staple of any modern amplifier?

2. Is it possible that all Phoneix Gold amps have MOSFET technology and therefore they don't even mention it?

I know that MOSFET is an ackronym for the transistor used in amps; but to be honest with everyone, I don't even know what the hell a transistor is.

If the pros could enlighten me, I would certainly appreciate it.

they use them in there power supply

and in the outputs..

Usually Mosfets in the Power supply
switch on and off.
There are usually a pair or more on each end of the transformer. The transistors alternate(switching on and off)and send power to ground(chassi ground).
This process turns DC current into an ac wave form. (well actually a square wave)

With the outputs, transistors mimic the input voltage thats applied from your deck.
Fist, it goes to a voltage amplifying transistor, and then from there it goes to a current amplifying transistors (Usually today its a Mosfet but there are a handful of technologies that can do this stage))

The octane & Tantrum amps do use Mosfets for the powersupply and output sections.

The Ti's, ZX, M & MS amps use Bipolar devices in the output stage, similar to that of the Linear power amps. Powersupply stays as Mosfet though.

Awesome everyone, thanks for the help.
