Thirty-five watts of single-ended authority. Our finest design yet.

Fifteen years of development have gone into this design, and you can tell.

Built around the legendary 805A transmitting tube, Paradyne is the most powerful amplifier kit we have ever offered. At 35 watts per channel, delivered through a true single-ended monoblock topology, it produces twice the power of a Kaiju run as monoblocks, and almost four times the output of a single Kaiju amplifier.

This is a big step forward for our kits.

Single-ended amplifiers are prized for immediacy, tone density, and realism but they are rarely associated with real power. Paradyne was created to challenge that assumption.

Paradyne was designed by the holy trinity of legendary audio gurus Paul Birkeland, Paul Joppa, and Dan Schmalle. By combining the brute force of the 805A with a carefully considered driver and output stage using 7L7 and 6BL7 tubes, Paradyne delivers headroom, control, and scale that redefine what a single-ended amplifier can do with a wide range of loudspeakers. The result is an amplifier that retains the harmonic richness Bottlehead is known for while driving speakers that would have been unthinkable with earlier designs.

Iron Maidens

Paradyne includes all-new, Bottlehead-designed iron. That means you're getting a cutting edge power transformer, our beefiest output transformer, and a new and improved plate choke. This new suite of iron provides performance gains over previous designs, and allows for switching output impedances by moving one ring terminal instead of re-wiring the secondary.

Purpose-Built Monoblocks

Each Paradyne kit includes a pair of monoblocks, because this amplifier was never meant to be compromised by a shared power supply or layout constraints. Separating the layout into two chassis allowed us to provide:

• Dedicated power and output stages per channel
• Shorter signal paths
• Greater channel separation
• Absolute focus on performance
• Easier user serviceability

This is power done properly.

These amps ship in two separate, well packed, insured boxes to ensure we can protect the components (and because they're heavy). Once shipped you'll get separate tracking codes for each box.

This product has a universal power transformer and can be used worldwide.  Please note that international customers will need to provide their own power cord.
