⭕ I have owned this preamp for about 3 years from new. It sounds fantastic and is in like new condition having been on well ventilated racks, not moved, and not used very much. This TUBE Mk II preamplifier has been serviced and upgrade by Einstein in Germany. All tubes are within specification. If not happy with the unit, returns accepted within 30 days. Will help with shipping or collection welcome. It is complete with the original wooden and cardboard shipping boxes. The shipping exterior box is 28 x 28 x 18 and weights 80 lbs. You wont be disappointed!
