• Notes
• The Crosley Harko Sr. V, also written as Harko Senior V (or 5) has one dial (primary tuning control knob) and is a non-regenerative audion. Cabinet work, Adam brown mahogany finish. A "Crosley 2 Step Amplifier" was also offered as a match with it. In Summer 1922 the sunspot interference peaked and sets without regeneration had poor and only local reception. The answer with an audio amplifier was not the right one for this problem, but Crosley then had no choice - see this text about Crosley - with more details and overviews. Careful: There are different versions and also regenerative versions (Tri-City version and Precision Equipment version in 1923).
