Description
This 1972 AM domestic radio receiver only has 3 tubes and no transistors.
The three tubes are :
1. 6AN7 (Osc/Mixer)
2. 6N8 (Detector, AGC, IF).
3. 6GV8 (Audio output tube
It doesn't have a rectifier tube because the rectifier is a solid-state device mounted under the chassis.
There is only ONE knob on the front panel which acts as an On/Off switch and volume control. Tuning is carried out by manually rotating the front dial indicator.
The type and model of this 3 tube radio is mentioned in the video.
There are still original resistors and wax type capacitors under the chassis !
The speaker is a 4 inch MSP permanent magnet type
The received signal is quite reasonable with only a very slight amount of hum in the background. It uses an internal ferrite rod antenna.
