Marantz 7T recommendation

This is not a direct answer since I didn’t have one restored (though I did have a tube one that ’got away’ back in 1973), but you may still find this of interest. Guy bought a 7 knowing it was frankensteined by a mod that converted an output circuit to solid state. Audio Classics brought it back to original state. Pretty impressive. https://forums.stevehoffman.tv/threads/undoing-the-worst-diy-mod-ever-update-audio-classics-to-the-rescue.666161/#post-16308646
