It has come to our attention that a 240V Paramount operated under 230V may not produce sufficient filament voltage (2.4V DC for 2A3, 4.75V DC for 300B between pins A1 and A4).
If you observe this issue, a capacitor can be added on the FC-1, between terminals 5 and terminal 10, with the striped lead on 5 and unstriped lead on 10. This capacitor should be rated at 6.3V or more, and sized around 4,700uF to 10,000uF.
Do not add this capacitor if your filament voltages are within tolerance stated above.
