Gates Executive Audio Console Rebuild

Submitted by: Jerry Whitaker

According to Jerry:
This project is a rebuild of the Gates Executive Stereo Audio Console. Manufactured in the late 1960s through 1970s, the Executive was the largest console of its type offered for sale by Gates Radio, a major broadcast equipment supplier of the time. In order to bring the console back to useful service, it was necessary to remanufacture many of the circuit boards. I selected the Hammond 560 series of broadcast transformers. Two of the new boards (one with a 560C and the other with a 560G) are shown in the attached photo. The main card cage for the console includes 11 of these boards, as shown in an attached photo. I have had very good luck with the 560 series of transformers. They perform very well. I will be using them for other projects going forward.
