• Model: Aristona V4A - NSF Nederlandsche

• Notes

• REMARK: This model is comparable with Philips(NL) V4A and Philips(F) V4A. It has the same circuitry as them which means that the author (P.H. Brans) of the schematic present with this model probably has forgotten or judged it necessary to omit the "A", especially because model V4U (any brand) is not listed in Brans. Author Cortenberghe does list the model as V4A and also lists the V4U. Authors Brans and Cortenberghe are in disagreement in case of this model. Radiomuseum.org includes type V4 along V4A because there is a source for it.
