Aa5 Radio Signal Flow -

While not directly in the "audio path," it is vital for flow. It converts AC house current into the DC voltage (B+) required by the other four tubes to function. ⚠️ Critical Safety Note

It creates an Automatic Volume Control voltage to keep volume steady. AA5 Radio Signal Flow

It "strips" the radio carrier wave away, leaving only the Audio Signal (the music or voice). While not directly in the "audio path," it is vital for flow

The signal travels through an Output Transformer (to match impedance) and into the Speaker . 5. Rectifier (The Power Supply) Tube: 35Z5 (or 35W4) AA5 Radio Signal Flow
