Available from my Marantz collection: Marantz 7 Tube preamplifier-serial # 7-21751. This legendary and iconic preamp is in excellent condition. It was acquired 5 years ago from the original owner(CBS music sr.vp) -the on switch has been adjusted to always be on (set by orig. owner-). I will install 6 brand new factory matched Mullard(russian) 12ax7's for the purchaser. Sent with this unit will be color copies of the instruction manual and factory promo sheet. The original's of the rare electrical performance spec card, and golden warranty certificate, specific to this unit will also be included. The preamp will be extremely well packaged and sent USPS priority mail.Pymt.via USPS MO. Thank you for your interest.--PS-the dark streaks on the first picture are shadows from the switches-Faceplate is excellent like the other sides.
