Pre-Amplifier with deisign and quality

Enjoy the understated body with smooth touch.
Not only sound, but also appearance highly cared pre-amplifier.
For those who want to enjoy real sound.

【 Features 】

It has "T.A.L.T" inside.

What is "T.A.L.T" ?
T.A.L.T.--"Technocraft Active Load Thechology" is invented by Technocraft Audiodesign.
It is a circuitry that SRPP inputs and its cathodes of upper and beloew are directly connected to output grid, which looks very similar to SEPP.
This circuitry realizes low output impedance with high input impedance, which help to make musical details very clear and natural.


Remote Control
Function--volume, selector, mute.
When manual mode, cut off elecricity to remote circuitry to keep clearer sound.

Safety Shield Structure
Vacuum tube's life duration depends on thermal circumstances.
To avoid high temperature circumstances, set vacuum tubes horizontally in a chimney structure, releasing heat effectively.
Around the chimney, set power transformer and remote control circuitry, power section on the side, amplifier circuitry on the rear. This each part shileded structure raise signal-to-noise ratio which is so sensitive that doesn't even appear in numeric.

Use film capacitor
For all power capacitor of amplifiers, film capacitors are set. We use them instead of electrolytic capacitor, considering btternment of musical expression and life duration.

Use high grade double-sided epoxy-glass throughhole board
Thick beaten-copper 70μm epoxy board is used. Avoiding resist processing that cause would cause adverse effect on music, use gold-plating processing for patterning.
The pattern of ground wiring is designed in radial pattern from each tube's operating point.

Latching relay for a selector
Using an audio changeover relay that is set near the input terminal, inputs changeover is controlled. Because of this, wiring of this part becomes shorter which means less degradation of sound quality.
To avoid permanent electric current's flowing into a coil that would cause noise, loaded an invented timing changeover circuitry. This is a wise circuitry that provide current to the relay drive only while selector changing, and cut out current a few seconds later.

Care about small vlume
User-friendly continuous variable volume is selected.
What is often said is that with a continuous variable volume, not only sound but also quality goes down. But we have our original circuitry that allows only sound to be smaller and keep quality high.

Pre-Amplifier with deisign and quality

Simple and weariless design
With smooth toutch and quality sound.
This is the first mass production of Technocraft Audiodesign.

Not for producer's convenience, but onsidering to "reproduce music as music", it was designed.
This is theamplifier that can bring out musicians' feelings and passion.

High-fidelity

Most necessary minimal materials and functionsf for higher clarity.
Not like exisiting models, original cool design.
・White grey colored front panel,top board is black alumite.
・Excluding SP terminal post, switches, legs, knobs, body is same LP size as MODEL 1a.
Not like usual vacuum tube amps which sound is blur, sharp and clear like semiconductor amps but not awkward like them.
You should check it out with your own ears!

With just 7.5Woutput, play orchestra.

With only 7.5Woutput?
Whole orchestra?
No way!
Yes way!
Those who are told it's 7.5 output after listening to it, theyare amazed.
It became possible because of our original circuitry "T.A.L.T.".
You should confirm with your own ears.

【Features】
"T.A.L.T"

This circuitry realizes low output impedance with high input impedance, which help to make musical details very clear and natural.

Only one coupling capacitor
With direct coupling from the drive to output, avoid unnecessary coupling capacitor which cause phase distortion and increase of circuitry time constant. As a consequence, kickout turbid and make sound transparent.

Ppower source transformers for each left and right channels.
Transformers for each channels makes clearer sound that single transformer equipped amps.

Use high grade double-sided epoxy-glass throughhole board
Thick beaten-copper 70μm epoxy board is used. Avoiding resist processing that cause would cause adverse effect on music, use gold-plating processing for patterning.
