    What vintage speakers are you using with your Marantz receiver?

    Marantz 2220b phono hum

    First post from novice DIY. I replaced the lights and cleaned the connectors on my wife's original 2220b receiver and it sounds much better. During testing, I noticed a significant hum from the phono selector with no external turntable or other inputs attached. It was very noticeable at 1/4...

    Cartridge Recommendations to go with Marantz 6350 TT and Marantz 2235 Pre?

    Howdy! I’ve tried a AT VM95E, Ortofon 2m Red, and a Sumiko Black Pearl. Looking for more clarity and dynamic range, but don't want overkill for my setup. Budget up to $300 but could push higher if persuaded... Thanks for any suggestions!

    Marantz Model 25 Project

    I bought a Marantz Model 25 last month and it actually sounds and looks great, so I've been using it as my main system while I finish work on a couple other receivers. But this thing is supposedly from around 1969-1971, so it surely needs to be re-capped at minimum. I'll document the process...
