WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Today I bought this small phono preamp.
Inside are 4 EF80 (per channel), triode strapped in SRPP configuration. At the end is DIY LCR 600 EQ.
I tried all day to find similar schematics but with no success.
Anybody familiar with this schematic?
