Here we have a Beautiful condition, one owner, no pet Mcintosh C-11! The holy grail of preamps! We bought it from a long time customer of ours and were delighted with the condition, ! The owner gave us along with this gem, 4 new tubes which are now in the preamp along with 2 NOS. Telefunkens. This beauty has been completely serviced and all factory recommended upgrades were installed. Included in the restoration are all new (higher quality) electrolytic capacitors throughout. Ultrafast soft recovery rectification. New 1% Mil-spec Dale metal film and Xicon resistors in the power supply. The phono section's inferior sounding ceramic caps were upgraded with period correct polystyrene film and foil caps and ultra quiet  Vishay and Caddock .1% metal film (non inductive) resistors ($$$$). All mylar tube caps were upgraded to Wima polypropylene `film caps . All the switches and potentiometers were cleaned and lubricated. All inferior mylar coupling capacitors were upgraded to period correct Orange drop Polypropylene film and foil caps. ( smoother while still maintaining the magical Mcintosh Lush sound). Lastly the owner had replaced the front panel lighting with LED units recently. There is a reason why these preamps are considered within the top 5 collectible audio components of all time, they sound great, they look great and when professionally serviced and upgraded as this one is, will last another 50 years or more and continue to beat the stock market as an investment. If you have been waiting for one of these in very nice shape both cosmetically and functionally, this is the one. Discounts for both Cash, Zelle, Paypal F and F transactions and local pick-up.
