[Music in a bottle]

I finally couldn't stand it any longer, and tore into my dual mono block Marantz model 15 from 1968! It had been making a mechanical sounding thump on power up, and I was concerned it was the power transformer in one of the modules. After an extensive process of elimination, I discovered that at least one of the two power electrolytic capacitors was dried up and needing replacement. For a guy with no electronics experience, I feel like rewinding the RF coils in my Philco 7o now! I still have yet to find 4 new caps that will fit in the space in my amps! They're unusual!
