Valve Amplifier Study 010: Vacuum Tube Microphone Pre-Amplifier RCA 5AR4 (12AY7)
Here we have our audio service technician taking you through a voltage amplifier. The RCA 5AR4 circuit employs two 12AY7 double triode valves which have the military equivalent 6072A.
Our next video will be another vintage valve amplifier, the British AC/SP3A Microphone Pre-Amplifier.
We have many more videos to upload covering a wide variety of vintage British & International audio circuits for hi-fi and recording studios.
