I've restored these 1500s inside and out. Recapped and rewired the crossovers and made them point to point. Cleaned/deoxy'd all attenuation and frequency switches. All drivers shine with sound. Sanded and restored the cabinets to their original walnut veneer with 5 coats of naptha/poly. Grills are in excellent condition and I've made them removable using velcro dots that blend into the cabinet. I'll include/install heavy duty rubber sound isolation feet if you meet my price. Buy with confidence from a musician and audiophile.
