Last night I received a new arrival from Ebay: A $25 Beomaster 2400.
Oh. My. God. It's not in pristine cosmetic shape, but all the lamps burn bright, there is no flaw in the sound, all sliders are noiseless and work. Switches all seem to work. I haven't hooked up a phonograph or line level source (yet), but the tuner works perfectly.
The refurbed S40s now have a temporary home providing radio playback in the garage while I recap/relamp my other Beomaster 2400.
$25. What a steal!
(PS - Klipsch kg2's make nice stands for the Beovox S40s!)
Current primary listening: SMMC20EN -> BG4002 -> BM4000 -> Beovox M70
