re: 4230

THANKS for the manuals. I bought my Marantz 4230 new in about 1974 but it didn't come with a manual. I tried for several years to get one but never managed to so I finally gave up. I am happy to have found this one here since I recently had mine upgraded and tuned up. NOW I will finally know how to use it RIGHT! :-)

re: 4230

I also bought my 4230 in 1974, ordered it at the AAFES in Athens,Greece. Had it drop shipped home, where my brother blew out the left channels "testing it" while I was overseas. When I got home it had been repaired, apparently not right. It failed again, so I bought all of the manuals back then. It had been sitting in storage until now and since I am finding time now to repair it, I am anxious to get it working again. My unit is very "low mileage", since I didn't get a chance to use it much. The visible beauty of the unit powered on is what sold me on this unit, not to mentioned that distinctive Marantz sound. I am happy to find this web site and the generous people that donate documentation, we have to keep this equipment alive. Their classics!
