Θεριό" tube preamp (Therio). A modified Model-T 1st-gen amplifier, including the phase inverter and the NFL.
Additions:
- HI/LO gain switches for both channels
- Brite switch for the Normal channel
- Treble Bleed switch (3 positions) for the Normal channel
- Negative Feedback Loop selection switch (3 positions)

2 Outputs for power amps have been included. Each output has its own dedicated output level control.

The preamp is AC powered with either 230V or 120V (selectable through a switch on the back side).

custom built for @1000mods

(The galvanized steel angles shown in the photos were added for fixing the preamp on a rack shelf)

КТИΝОΣ tube preamp (ktinos). The circuit is the preamp of the Model-T 1st-gen amplifier including the phase inverter which is a crucial part of the original circuit and plays a significant role for gain, tone and presence control.

4 Outputs for power amps have been included, two for each output of the phase inverter (0 / 180). Each output has its own dedicated output level control.

The preamp is AC powered with either 230V or 120V, selectable through a switch on the back side.

This is the mini Buffer with variable output Impedance and it's suitable for use with a guitar, bass and any other instrument with similar pickups.
A buffer is a circuit where the output is the same as the input. The "secret" is that this particular buffer circuit has a very high input impedance (10Mohm) and variable output impedance (0~220kohm).

Without getting into many details this eventually means that it improves the high frequency response of your overall pedal chain so that you don't lose your tone as your highs aren't getting sucked up.

Additionally, through its single knob you can adjust its output impedance to match the output impedance of your guitar pickups so that any pedal (e.g. a vintage fuzz, or any low input impedance pedal) that comes after the buffer behaves in the same manner as when you connect the guitar directly to it.

A buffer can also help you run long cords without risking losing tone or making your sound bassy and muffled

- Input impedance: 10Mohm (constant)
- Output Impedance: variable 0~220kohm
- Voltage Required: DC 9-24 Volt (Use 12-24V for more headroom)
- Max Current draw: 4mA @ 9 volts
- Aluminum Enclosure, dimensions: 93 x 38 x 32mm (3.66 x 1.49 x 1.26in)

It's always great when people that use the stuff you make send you photos of their gear setups. Here is a massive one with two dpFX builds in it: the 4x4 Matrix Mixer and the Multi-EQ preamp (Many thanks to Matt for the photos)

Rack Splitter/Router with FX Loop & XLR out.
This is a custom splitter/router with FX Loop that can handle signals ranging from instrument level up to higher line level.

It is equipped with 4 TS inputs, 4 TS outputs, 1 FX Loop (2xTS), a Tuner-out and a Balanced XLR-out.
By using the respective rotary switch you can select which input and which output will be active each time. (check flow chart).

It features high-impedance inputs (buffered with JFET, low noise Op Amps) that can be driven either by instruments (guitar, bass etc) or line level signals as well.
The output impedance is very low, ensuring the best interconnectivity with the rest of your gear.

The circuit is built around low noise, low distortion OP amps and is equipped with input filters in order to reject external RF interference.
It requires a typical 9V power supply and can take up to 24V (max).
The higher the voltage the larger the available headroom.

Headroom vs supply:
~6Vpp@9V
~10Vpp@12V
~16Vpp@18V~22Vpp@24V

- Input impedance: 3.3MΩ
- Output impedance: 100Ω
- Balanced output impedance: 150Ω
- Flat Frequency response on the whole span of the audio spectrum.
- Required power supply: 9-24 Volt DC
- Current draw: 12mA @ 9Volts
- Enclosure dimensions: 19" 1U 431x203x43mm
- Weight: 1055gr
