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.

KONSERT. A preamp in a pedal, based on the preamp of the Sunn Concert amplifier (Lead / Bass).
The circuit of this pedal is a replica of the preamp used by Sunn for the Concert Lead and Concert Bass amplifier.
The original schematics were used and a couple of more features were added to make it more versatile.
Volume, Boost and Distort and EQ functions are exactly set (circuitwise) as in the original circuit.
Internally, an extra power supply circuit was added in order to provide the necessary dual rail supply voltages that the original premp was using. All you need is the typical 9V power supply you use for your pedals.

**** Added features:
- Instrument Out. Use this output to connect the preamp to your pedals.
- Line Out. Use this output to connect the preamp directly to a power amp.
- XLR Out. Balanced output for connection with audio consoles etc.

Knobs & switches:
- D: Drive gain (works anti-clockwise)
- V: Volume
- B: Bass
- M: Mids
- T: Treble
- Brite toggle switch: Change the input setting Normal/Brite.
- Treble Boost toggle switch: Brighten your sound even more.
- Left footswitch: It acts as a bypass for the Instr.-Out and as a mute
for the Line-Out and the XLR-out.
- Middle footswitch: Boost ON/OFF
- Right footswitch: Distort ON/OFF

▹ Voltage Required: DC 9 Volt
▹ Polarity: Negative tip
▹ Current consumption: 65mA
▹ Weight: ~450gr
▹ Enclosure dimensions: 95 x 151 x 35 mm (3.74 x 5.95 x 1.38 in)

"OLETHROS II" Beta Bass & Beta Lead preamp (separately selectable for each channel), plus a 3-setting mids-shift function.

What's new:
• a toggle switch for each channel lets you select between the Beta Lead and the Beta Bass version.
• a 3-position toggle switch lets you shift the mids in a different
point of the spectrum: 550Hz, 850Hz, 1200Hz.
• Besides the LINE out which is used to connect the OLETHROS with a power amp an INSTRUMENT output has been added so that you can easily use it as a pedal.

- Alternatively an INSTRUMENT output is also available in case you need to use the preamp as a pedal.
- A balanced output has been added and it's accessible through an XLR connector. The balanced output's level is not affected by the Master knob.
