    Hi
    Looking for comment, advice, assistance retrofitting transistorizing pre 1930’s Tube Radios to lower safer voltages

    AntiqueRadio Tube Replacment/Substituion
    Hi
    I am seeking help, advice assistance and comment on replacing ALL the Tubes in Antique Radios with Transistor/Semiconductors that will operate at lower, safer voltages.
    The main target is the RF Stages of TRF Radios and to a lesser extent Regenerative Receivers.
    Detection and Audio will be handled by a simple Detector (Crystal) and Audio Amplifiers on a small PC Board readily available on Ebay.
    I want to explore the idea of using Radios on a Chip and receiver PC Boards using “Radio on a Chip” chips. Picking up the RF at the input to the detector/audio amplifier and shunting off theunused audio to ground
    TRF radios with 2, 3, & 4 Tuned RF Stages; like the Atwater Kent Models 20C and 30
    Regenerative Receivers Radiola III, Radiola IIIA and Westinghouse RADA
    Thanx
