Notes We received yet only the pictures and are not sure about the tube line up. We don't know the country of manufacturing, which could as well be for instance Brazil. But for sure it is a Mullard batched model. The EBL type was changed later in the set we know against an EBL21 and we have no information about the Magic Eye. More often you see the EF5 instead of the shown EF9 here (which probably has been changed here) and we found the model Aristona H57A from NSF to have the same cabinet with that tube line up - and it is probably equal in the inside. The same cabinet has also the Swiss Mediator M57A (see small differences how the back wall is mounted) and inside is probably also the same. Therefore we have corrected the tube line up found in this set from EF9 to EF5, the original one.
