- Notes
- This combination was proposed in an ad in "Radio Broadcast", August 1922 and in September 1922 in "Radio News". In the September ad Crosley features a total of 8 combinations. This combination of "Harko Sr." plus "R.F.T.A." plus "Two-Step Amplifier" is technically the same as a model X. The "2-Step A.F.Amp." has no front switch to select the number of active tubes but the combination can naturally also be done with the older model.
