With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

This solid-state push-pull single-ended Class A circuit is capable of providing a sound comparable to those valve amplifiers, delivering more output power (6.9W measured across a 8 Ohm loudspeaker ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

CES Innovations Awards Honoree – Azur 840W Class XD power amplifier — Suggested retail price – $1900 ex sales tax; £1000/€1900 inc VAT — Available Spring 2008 Cambridge Audio has taken the Azur 840 ...

Grand Rapids, Mich. – Pangea Audio combined a hybrid tube/solid-state headphone amp with a 192/24 USB DAC to create the $299 HP201, which joins a $199 model. The $299 HP201 and $199 HP101 combine a ...

Those 40-watts of Class A/B power can drive that single 12" Voice Of The World speaker hard, with plenty of juice for gigging – and there's onboard tremolo and reverb to sweeten the deal When you ...

The Class E power amplifier can be turned into an efficient, tuned-input, tuned-output (TITO) oscillator with the addition of a tuned circuit at its gate. The oscillator/amplifier has a power-added ...

Fig 1. This basic source-follower circuit is the kind of amplifier you would find in an electric bass guitar amplifier. R6 provides the feedback. On the other hand, low-distortion applications require ...

Conventional wisdom has it that the solid state era in electronics began in 1948 with the invention of the transistor, or if you wish to split hairs, with the 1930s invention by the Russian [Oleg ...

Copland has followed up its CSA 100 and top-of-the-line CSA 150 integrated amplifiers with an entry-level model. Unlike its hybrid siblings, the new CSA70 doesn't use tubes in the line stage, opting ...
