| Beschreibung |
These tubes use an inverted half cylinder for the anode, below which is a coiled grid aboved the arced filament.
The tests by Wireless World indicated that there was little or no difference between a sample of the Mullard HF and LF valves. The curves were almost identical and their performance in a receiver was the same when the RF and AF stages were interchanged.
