Yes, agree - also given the lack of description circa £200 is all about it warrants as it will be around 30 years old and thence a risk. A freshly serviced one ought be to be worth at least mint Exposure X integrated territory (although it is much superior IME). Musically it is as fun but much more powerful/dynamic than a Nait 2, and mine replaced and easily outboogied an Avondale power-supplied SuperNait. It does dynamic contrasts really, really well. My Nebula needs a service - but need to find it first (I've "mislaid" it after emptying out and converting my loft). Ampdoctor.co.uk is an ex-Linx engineer and can service these. He did my Linx Stratos pre-power amps.
