Hi, a friend of mine is selling his M77 clone PCB, it has all the phono and PSU modifications I talked about in this other thread https://www.diyaudio.com/community/...hone-preamp-clone-project.358732/post-6748859 , that means, the darlington heater regulator and the RIAA modifications. 4 tubes are included (as he only used the phono section). The line stage was tried and works, but, as said, only 4 tubes included. It comes with a low noise, potted toroid power transformer.
PM me if you are interested!
