I replaced some of the wiring and capacitors and the performance marginally improved so I left it at that. Many years later I decided to tackle the receiver again. This time I wanted to fully restore it as close to its original condition as possible both inside and out. That meant meticulously following the original diagram and layout, replacing the wiring and almost every component. The mechanical parts were stripped, revamped, cleaned polished and restored. I wanted the set to look good too, so I had to attend to the holes in the cabinet before spraying it with black wrinkle finish paint. This was followed by restoration of the receiver's trademark, the famous HRO tuning dial and finally full tuning and alignment. It was a long and painstaking project, but very satisfying.
