From the vendor
A compact tube guitar preamp. Two channels (Clean and Lead), two Lead channel gain modes (Low/Hihg). Each channel has Gain and Volume controls, as well as a three-band EQ. ECC83/12AX7 or 6Н2П-ЕВ tubes (2 pcs) are used. 6Н2П-ЕВ/12AX7 switchable heater via jumpers on the tube board. There are several variants for assembly the lead channel: E530/E430/E650/E625/E645. Power supply: regulated mains adapter 12 VDC (load current of 1 A or more). To power the tube plates an internal DC-DC high voltage boost power converter is used (Nixie type). The dimensions of the main PCB 99 x 134 mm. Enclosure type: Hammond 1590XX.
