Tuesday Tube : 4043C STC (Standard Telephones & Cables)

4043C/CV1448 is DHT tube that use the same filament specification (7.5V/1.25A)
as 10 series tube (10/10Y/210/801A/841/etc.).
Highest maximum plate dissipation rating 35W compare 10Y/VT-25 (12W) 
and 801A/VT-62 (20W).
Same UX-4 base like 10 series too. Black mono plate with ^^^ filament.
Very linear triode characteristic curve. 
Nice to make DIY project like Class A2 Single Ended Amplifier. 
Will get output power more than 6W !








Very linear curve !
