Sensibly equivalent to:
AT75 CV1222 CV2825 E472+D3157 NT39
    
Extras ▼

 

The ACT6 is a air cooled power triode. The anode dissipation is 75 Watts and the design is for HF use up to 37 MHz at 75% of maximum rating.
The four pin bayonet base. The external copper anode is fitted with a corrugated heat sink.
In addition to ACT6 the glass also has etched into it the experimental Type of E472.
The other side of the glass has the word Factory - probably indicating a sample.
The screw top cap anode connection.
The external anode envelope is 45 mm in diameter and, excluding the base pins, is 197 mm tall.
