One of my favorites! Marantz 2325 gets Sparkos Labs BA312-M upgrade, new lamps, and more!

It's always a good day when there's a nearly perfect vintage Marantz on the bench! The 2325 was Marantz's first "entrant" into the monster receiver wars of the 1970s, meaning this was their first receiver rated at over 100 RMS watts per channel. 125 to be exact! That's quite a big step up from the Marantz 2270 and 2275. In this video, I make sure this one is working well after years of storage. Enjoy!
