42 watts/channel ultralinear, 21 watt/channel triode, controlled via remote.

 

New global zero negative feedback design being an evolution of DiaLogue One with novel phase splitter and driver stage implementation.

 

PrimaLuna Adaptive Auto Bias Board with integrated plate fuse for hassle free protection.

Low noise, high current driver stage for higher power bandwidth, very low phase distortion and superior impulse behaviour.

 

PrimaLuna designed wideband and matched low loss DiaLogue output transformers with optimized phase characteristics.

 

Amplifier can be used in Ultralinear or Triode mode and is supplied with full UL/TR function heavy metal remote control.

 

Features:

 

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.

 

Zero negative feedback - makes for a more lifelike clarity and natural tonality.
