This listing is for a Doepfer A-108, a really flexible Moog style transistor ladder filter with its distinctive features being outputs with 6, 12, 24 and 48 dB simultaneously, three CV inputs for frequency control - two of them equipped with attenuators, and an external feedback input that enables the insertion of additional modules into the feedback path. Essentially, it’s Moog-like but much more varied and flexible than anything offered by Moog. Having tried many filters over the years it’s a personal favourite and I’m selling it only because I’ve recently got (almost) the same but in stereo. It’s fully working and a power cable is included.
