I've had most all tuners Marantz made in the 70s. Some of the better Marantz tuners I currently have are the 120B, 150 and 2130 (also have the Esotecs that are very close to the same as the 2130.)
The best with a scope is the 2130 of course. But which model you select, is just a matter of where you've set the budget, or what has come up for sale when it works for you.
I use tuners almost exclusively in my shop. Always have some station on while working. Fm stereo comes in very well here, so I take advantage of it.
Most all brands of vintage tuners need an alignment, and maybe a little repair work. It's surprising how much better they can preform if gone through. You don't really need to get into "mods" to get a pretty good unit.
If you want to heavily modify one, that's a whole other program
Even an expensive tuner can sound average, if not renewed back to original specs. .......These things aren't new anymore ! :thmbsp:
