Whammerdyne Truth

The Ultimate 2A3 Single Ended Triode Amplifier

Truth in Audio

Whammerdyne 2a3 Amp
close up of 2a3 and 6dj8 tube on whammerdyne truth amp

Multi-Purpose System Status Meter

Indicates warm up and operate condition
(Lights red warm up, white operate)

Real-time display of tube current

"Green" zones for easy visual calibration

Out of the audio signal path

Doubles as built in real time in-circuit tube tester

Custom made for Whammerdyne; base meter is the famous Simpson type (USA)

LED illumination lasts a lifetime

Calibration & Settings Selection

Unique out-of-audio signal path circuit

Selecting A or D monitors real time left or right 2A3 tube current

Selecting B or C monitors real time left and right half 6DJ8 tube current

Continuous monitoring of any tube's operating condition

Used in conjunction when running precision amplifier calibration process

The Fabulous 6DJ8/6922 Vacuum Tube

One single tube supported by an Ultra-Wideband proprietary circuit

NOS (New Old Stock) tube

Carefully selected for matched gain and ultra-low noise

This tube is cradled in a perfect environment

Kept at a current that is optimal for long life and very linear operation

Run with its own pure DC filament supply

Expected tube life 3,000 - 4,000 hours

The Fabulous 2A3 Vacuum Tube

NOS (New Old Stock)

The pair of 2A3s are matched for gain and current

In our opinion, the best sounding tube of all time

Each 2A3 has an independent pure DC heater power supply (Ultra low noise)

Tightly-controlled support voltage allow for perfect environment for peak tube performance

Six month warranty on the tubes

Expected tube life over 2,000 hours

Run/Calibrate Switch

Part of our "E-Z" amplifier bias and calibration system

Totally out of the audio signal path in Run mode

In Calibration mode (CAL) it's ready for the bias and calibration

A very unique feature by us for the (E-Z) precision settings process

Main Power

Press for on (latches in on position). Press again for off

LED lighted for on power indication

On initiates the amplifer warmup timer system (4 minutes)

Upon warmup cycle completion timer goes 100% silent (no noise generated by timer clock circuits)

Amplifier is now in full run operation

When amplifier is powered off it's really off - no standby power drain

Twin Audio Level & Relative Power Meters

Unique out-of-audio signal drive circuits

Custom made for Whammerdyne; base meter is the famous Simpson type (USA)

Controlled ballistics for great low-level volume sensitivity and damping for high-level

Auto level sensitivity circuit

Full range on meter is relative to 6 watts of delivered power into an 8 ohm speaker load

LED Illumination lasts a lifetime

Unique Stepped Autoformer Volume Controls

Each left & right channel is 100% isolated (Think duo-mono)

Each is isolated from all transformers and other noise sources

Top control knob has a 12-step rotary switch, providiing a range from 0 dB to a full -45 dB of attenuation

Lower control knob (fine trim) has a 3-step rotary switch allowing finer attenuation, steps of 0 dB / -1.25 dB / -2.5 dB

By using either left or right lower controls precision balance can be achieved

The Autoformer's extremely wide bandwidth preserves the ultra-fine details in the music

Speaker Connection Terminals

Precision machined, specially plated and non-corroding

4 Ohm, Common, and 8 Ohm outputs (left & right channels)

Easily accommodate large spade lug ends speaker cables

Can be tightly secured, spades, and bananas

Easily accommodate "banana" style terminated speaker cables and are locking

Engraved lettering above the terminals makes for easy connections

Input Connections

Precision machined, specially plated and non-corroding

Spaced to accommodate even the largest interconnect cable ends

Engraved lettering for left and right channels

AC Line Power Connection

IEC style removable power cord style connector (special low contact resistance plating)

Especially selected for correct contact pressures and low impedance

Integral AC line protection fuse with spare fuse internal included

Mating main AC power cable is especially manufactured for us and is of very low impedance; brass contact based (not tin plated)

Machined Aluminum Chassis

Unique multi chamber internal design

Highest isolation between transformers

Unique thermal management

Air flow convection design

All aircraft precision CNC machined 6061 T6 aluminum

Heat transfer thermal mass stability

Anti-resonance and self-damping

100% "Faraday" shielding for critical electronics
