I’m looking for the ‘control’ knob (CW-AM-NFM-PHONO) for an HRO-50T, gray in color. I would also purchase a complete set of knobs (black or gray) or, failing that, an entire receiver in any condition with all knobs, black or gray. Can anyone assist? 73, Bob WØYVA http://www.isquare.com/personal_pages/ras-hardware.htm
