For your consideration. A vintage McIntosh C28 Solid State Stereo Preamplifier S/N 77X90. In VG, if not EX cosmetic condition. For a detailed look of the unit up close "
View listing photos & YouTube DEMO link
" Serviced & re-capped. Replaced low level inputs with gold plated RCA's. Upgraded with LED lights. There is some light bleed around volume knob. I have found taking a black sharpie to the outside glass covers up small imperfections & is virtually unnoticeable.
All service adjustments performed by a professional tech semi-retired with 45 years experience in high-end audio repairs to bring unit back to original factory specifications if not better.
All products are fully tested. Faulty or under-spec components are replaced with modern high grade equivalents. Any known issues or potential weak points are rectified up-front to ensure these products continue to 'sing' for many years to come.
Looks, sounds & performs beautifully. The unit shows signs of use, and is clean and working properly. That being said, due to the age of this device & the uncertain nature of vintage electronics. This unit is being sold as pictured/described. Item will ship insured with signature required. Thanks for looking!
