Radioconstructor: Power supply for lamp structures on a kenotron with an EMI filter

Provides power to lamp circuits with unstabilized anode and filament voltages:
Mains voltage: 220V/240V 50Hz.
Anode: 250V 75mA, constant current.
Filament: 6.3V 2A, AC.
Board size: 125 x 80 mm.
Built-in anti-interference (EMI) filter.
It is possible to supply a positive voltage through the filament circuit to combat the 50Hz background.
The kit is supplied as a printed circuit board and parts kit.
