Marvin55 Posted November 26, 2023 Posted November 26, 2023 (edited) This is a knockoff of a well known circuit, a Marantz 7 I think. The "documentation" rather bravely states "upgraded Mar. M7". 8Audio's website has a newer, different modified board detailed, and power supply advice at https://www.8audio-mall.com/finished-tube-preamp-pcb-design-upgraded-to-marantz-m7/ The kit comprises the built PCB that houses 2 x 12AX7 and 2 x 12AU7 (valves not included), a suitable Edcor transformer, a 24 position stereo attenuator of 50 K impedance, and a power supply. The power supply is more of a 3D sketch than an actual working device, so test it - it may work, or it may not... There is a sticker detailing the Edcor's windings, and there is a single A4 page outlining the PCB's circuit, and the company has a website at 8Audio.com. Please note that this is not a "Plug and Play kit"; it will require some expertise and patience to get it working. Shipping $19 Edited November 26, 2023 by marvin55 Forgot Photos!
