In 1932, Clifford A. Harvey W1RF started Hendricks & Harvey together with Paul S. Hendricks as partner. They seems to have meet each other at MIT. The only ad I have found from this company was this cute SSS receiver they made. If anyone has info about this receiver, please write me and tell.
It was constructed after articles of the Single Signal Super receiver by James Lamb in QST the same year. Way ahead of its time, 2 IF’s and a xtal filter + 8 tubes. This 3 years before the National HRO Sr was put into production with almost the same setup!
