Ha! I still own my Marantz 2285 receiver purchased in 1978. I have never had a problem with its performance. I took it in to a local shop a few years ago for a dusting and cleaning and replaced all the blue lights just out of principle! The receiver has a by-pass feature that allows you to utilize the unit as a pre-amp, which is how it is working today! I use a B&K amp under the Marantz. The system fires a pair of JBL L65 speakers, which are also pushing past the 25 year mark! This was my first stereo system, and I am planing to pass it down to one of my children!
