The Elac CD400 and CD500 were mentioned here before, I like those vintage 70's decks made by Nakamichi for the German Elac company. I recently found another CD500 (left in the picture) and today I received the CD520! This CD520 (right in the picture) is basically an upgraded version of the CD500, the limiter has gone and has been replaced by DNL, the Philips noise reduction that the early 70's Naks also used. The record/playback head has also been upgraded, it is called here FGO head, judging from the shape and mounting it is the same head as used in the early 70's Naks like 250, 350 and 550.
