70 watts/channel ultralinear, 40 watt/channel triode, controlled via remote.

 

The DiaLogue Seven shares much of its basic circuitry with the DiaLogue Five stereo power amp. The novel phase splitter and driver stage implementation have been adapted for monaural functionality in linearity, distortion, and power delivery. We accomplish this by using an industry unique dual feedback topology: Cross coupled current feedback for superior impulse behaviour and gain stability at any level.

 

We use very small amounts of negative feedback for a more precise gain setting, lower distortion, and lower output impedance. This feedback technology effectively cancels the byproducts of negative feedback, thus creating an amplifier circuit that gives you all the benefits of properly implemented feedback, but without the drawbacks.

 

Newly designed PrimaLuna wide band low loss DiaLogue output transformers designed to handle more difficult speaker loads. A 2 Ohm tap is included in addition to the 4 Ohm & 8 Ohm taps. As with all PrimaLuna amplifiers, the DiaLogue Seven comes standard with Adaptive Auto Bias, fuse protection, and soft start circuitry for extended tube life. As with the DiaLogue Five, the DiaLogue Seven also includes upgraded Solen capacitors, and fast recovery diodes in the power supply for the ultimate in detail and dynamics. Amplifier can be used in Ultralinear or Triode mode and is supplied with UL/TR function heavy metal remote control (one remote per pair of mono amps).

 

Features:

 

For a little more money over the DiaLogue Six you get:

  • Upgraded Solen capacitors made in France. The result is an even better midrange and clarity.
  • Fast Recovery Diodes. Resulting in increased definition and detail, especially when the music becomes complex.
  • KT88 Output Tubes. We use the current production copy of the legendary Genalex KT88.
  • This gives you a little more power, better bass control, and a little more extension at the frequency extremes and more air up top while still remaining incredibly smooth.

All PrimaLuna products feature:

 

Soft-start circuit - Extends component and tube life by powering up the amp gently every time you turn it on.

 

Tube plate fuse - Protects the amplifier output stage.

 

Adaptive AutoBias - Exclusive to PrimaLuna, this circuit monitors and adjusts bias automatically. Improved performance and better sound, with distortion reduced by 40% to 50% over conventional designs. Plug in virtually any power tube. Adaptive AutoBias will automatically adjust itself! In addition to EL-34s, you can use 6550, KT88, KT90, 6L6GC, KT66, 7581, EL37, and any of their equivalents.

 

Premium parts - Fully vented chassis, chassis-mounted ceramic tube sockets, Alps potentiometer, Nichicon and Realcap capacitors. WBT style speaker terminals. Gold plated input jacks. Hand made with the finest point to point wiring, with workmanship equal to or better than any product you can buy at any price, period.

 

Chassis made of finely finished heavy gauge steel, and five step automotive quality finish. Each coat hand rubbed and polished. Removable tube cage included.

 

Toroidal power transformer - for low hum, and a front end that is dead quiet.

 

Conservative design - runs tubes easy for long life.

 

DiaLogue series goes even further with:

 

Triode/Ultralinear switching - Allows you to switch how the power tubes operate on the fly via remote.

 

Improved output transformers - designed for wide-bandwidth and high efficiency. These heavy-duty transformers elicit incredible detail from top to bottom, lower the output impedance, and provide the amp with greater control over speakers with difficult loads.
