    The mains voltage selector has only 2 positions: 125 and 220 Volt. To select 110 or 200 Volt, R38 has to be shorted and the labels on the selector switch have to be exchanged.

    This model is based on Philips model 205U [Holz], just like NSF model Aristona H128U.

    There is also a Siera model S108U reported in a bakelite case, however it is unlikely that this ever existed. The booklet "Siera memento of tubes and models 1932-1946" only mentions the wooden model with a UY21 rectifier.

    Attention: chassis connected to the mains !
