content: Radiola RA regenerative tuner. It is built for use with the Radiola RA, but also may be used with the type AR RF amplifier. The case for the RT is of polished mahogany. Three binding posts at rear of cabinet make it possible to use either the condenser or the variometer separately or both, in either parallel or series connection. A condenser (not on this specimen) is normally furnished for use on back of RA tuner between antenna and ground ports for the purpose of converting the wavelength range on the RA section.
