RESTORATION DETAILS:
Cosmetically : Chassis professionally sanded, re-chrome-plated and re-printed with tough-as-nails ink (these are the ORIGINAL chassis, not the cheap, light-weight, sad-looking repros you find on ebay. Those repros weigh half a pound less than the originals, are printed with plastic letters that come off with a nail flick. Thin gauge, cheap plating, etc. Not good!) Black bases professionally powder-coated & transformers professionally painted (no smell).
Electronically restored:
Complete electronic restoration: all resistors replaced with same-value-as-originals carbon comp resistors, all new caps (combination of Sprague Atom electrolytic, caps in signal path are a combiunation of new paper in oil caps and polyproylne, polypropylene & mylar for bypass, silver mica for small values), new, German-made multi-section, 525v/550v can capacitor (power supply filtering), the tallest (for similar look as originals) and most expensive on the market (nothing glued to bottom of chassis — your Mcintosh amps deserve better). Pots cleaned and deox’d for noise free operation, new power cords & RCA jacks, all voltages checked and well within range of McIntosh factory specs. All transformers are original McIntosh of course.Warm, musical, as only vintage McIntosh can be. Super beefy, enormous soundstage, unbelievable detail & dynamics. Transformers run remarkably cool. No hum, no noise.
