Mystere pa11 Stereo Power Amplifier


Open stock but like-new! Full warranty!

When we break down our integrated amplifiers into separates, we offer much more than the pre- or power stage of that integrated. So while the pa11 power amp evolves from the critically-acclaimed ia11, it offers much more. For instance...

We once again offer 40 watts of pure pentode output per channel, maintaining all the glory and beauty of tubes. However, the transformers in the pa11 are completely different, providing much more efficient power that delivers incredible depth and punch. We do implement a very modest amount of global negative feedback to make the amp rock solid.

We also use a high power, low impedance, solid state rectification circuit followed by a massive pi network using the highest quality caps and resistors. In the signal path are only two high quality Solen coupling capacitors.

Finally, we implement Mystère’s proprietary Adaptive AutoBias circuit, specifically tuned for Pentode operation. Optimized for EL34s, the AutoBias circuit is continuously tweaking each tube to its sweet spot. No biasing, no need for matched tubes, no worries.
