The 402 is the companion pre-amplifier for the 702 power amplifier (see other page). There was also a 602 that did not have the tone controls. Everything is top quality! components, circuit board, controls and case work. Everything beautifully designed, especially for the era it was made. There is a superb phono stage that is switchable (internally) for Moving Magnet and Moving coil with external RCA plugs to add loading. Not sure why I did not have this on the website, it's been a part of my main system, McLaren, for a long time; this and the 702 sound superb and won't be going anywhere.
