I'm bumping this thread because I'm currently in this boat myself...have gone down a rabbit hole and am trying to build a 70's system.
First purchase was a Technics SU-7700. Not a ton of power, but think it will work well with some ADS speakers once it's recapped/refurbished.
Just purchased a Rotel RA-1412. Thing that got me interested was fully DC-coupled and it's also a dual-mono design with two transformers. Not sure which speakers but it would work well with the ADS (L910 or L810).
Then I just learned about the Gale 401A speakers and fell in love with the design. Was on some thread where someone who used to work in stereo shops in the 70's said they used to pair those with the Accuphase E202. I live in Tulsa and Paul at Many Moons Audio builds new driver boards for them, but I've heard the preamp section is only okay.
Anywho, wondering if there's anything else I should consider. Any piece of equipment I pick up will be thoroughly gone through by a tech.
