  There is also a model 569 with exactly the same cabinet and tube line up with the name Cleartone 579-1-58A, but we don't know the wholesaler, but the information "RMA Code No. 213" indicates for us that it was made by Detrola. It is a "brother" of this Stratovox 579-1-58A sold by Grossman Music Co. See also the model Meridian 579.
