Beautiful sounding preamplifier with great phono input. Is even suitable to connect a 2nd power amplifier or 2nd set of MFB speakers to. Very popular active speakers with 2 built-in power amplifiers per speaker. This sounds very beautiful and very mature despite the size. The tweeters as well as the woofers look neat and that can be heard as well. The cover are also still neat except for some small bits of damage. The match with the 22 AH 270 preamplifier is exceptionally good! Be there if you are interested, because they are in good technical condition. The speakers nicely switch on and off when there is a signal from the preamplifier and also nicely switch off when the signal is no longer there. The speakers as well as the preamplifier have some signs of wear, but that is no surprise considering the age. The preamplifier has been bumped in the right corner very slightly, but still looks very good and also does not affect its quality. Set will be supplied without RCA to DIN plugs.
