Single-ended tube circuits are straightforward and simple, providing the most organic, raw tube sounds possible. In contrast to the more powerful push-pull designs the output of single-ended circuits usually does not exceed 5 Watts. That is why single-ended circuits are mostly found in small practice amps preferred by many top-notch players for recording.
Main benefits of single-ended amps:
Dating back to the first days of vacuum tubes single-ended amplifiers are nothing new. However, the Palmer DREI incorporates THREE of these providing three times the output power of a standard single-ended design! Moreover, it accepts a variety of output tubes which all have their own unmistakable sound characteristics.
The EL84 is bright and “British” sounding with tons of distortion (think Vox amps), the 6V6 provides somewhat darker tones with a smoother “American” distortion flavor (think Fender), and while it is tight and bright at lower volumes the 6L6 becomes progressively darker when driven hard. With the Palmer DREI you can mix and match power tubes from three distinct amplifier tones and thus create your own voice.
The Palmer DREI works with the following power tubes:
Three different single-ended amps in a single unit - that's the Palmer DREI formula!
