About the "4SH1"
It could really be a 4S11, Eq. to a E2d (4V, 1.5A filament) audio output
pentode.

Hi David,

ECH11 = 6.3V, 200mA filament
EF11 = 6.3V, 200mA filament
EBF11 = 6.3V, 200mA filament
4SH1 = 4V filament (see your own schematic) obviously an audio-output
pentode
EZ11 = 6.3V, 290mA filament dual rectifier.

Obviously not cold-cathode tubes.
Just almost-standard WWII German stuff.

The schematic in the photos lists valves:
ECH11, EF11, EBF11, 4SH1,EZ11

Another reference lists:
DCH11, DF11, DAF11, DY11

Are they really all Cold-Cathode valves?

Is there someone with experience on this radio?
Where can one find these valves?
