    The Sears Silvertone 1825 is an AC operated 14 tube BC and SW band receiver.  Has AVC and push-pull output using Qty(2) 45 tubes in parallel on each side of the output stage.

    Chassis and schematic used in this model also used in model 1828. Riders Sears 5-39, 40 schematic is for model 1828 but Sears Silvertone Service Manual 1928 thru 1936 confirms that models 1828 and 1825 use the same schematic, thus Riders schematic is valid for this model.  Also, Riders Index also confirms 5-39 as the schematic for this model.

    See details and summaries about Sears catalogs etc. This model was manufactured for Sears by Colonial Radio Corp., Buffalo, NY (Sears Manufacturer Source Number Code 101).
