If you are looking at this ad, you know the reputation of these amps. These amps specifically have quite a bit of discoloration and pitting (see detailed pictures); one of the Triad transformers has a dent. Per the original ad from DJL Vintage, these amps have been rebuilt with high quality parts and attached to custom solid American walnut platform with the Ampex logo from the console.
