  • Notes

  • The revolutionary ERLA Circloid - Five Factory - Bilt Kit

    This new type of kit is factory assembled. Ready-cut, flexible, solderless leads make it ridiculously easy to wire. Amazing new inductance principle brings results hardly thought possible. 

    Now, anyone can build the finest of receivers in only a few minutes. No more wire bending or soldering. Simply attach a few ready-cut, flexible eyeletted leads, and the job is done. The finished set is unsurpassed even by the costliest factory-built receiver. But most amazing is the new inductance principle incorporated in this last word in kits, called the Erla Circloid principle of amplification.

    Possibly the first ERLA Radio using the balloon Circloid coils.
