philips: Philips models 56A 57A and 58A

L.S.,

reading the data of this model I conclude that the Philips models 56A, 57A and 58A technically equal.
For model 58A only the rectifier tube is UY21 instead of the UY1 for the two other models.

So far my remarks.

Rectifier UY1 and  UY21 have different tube sockets and consequently they cannot be interchanged. For that reason model 58A is presented by RMorg as a separate model.

More important is that Philips will have had good reasons to give the models the designations 56A, 57A and 58A and even if we would not know the differences between the models, this is reason for RMorg to create 3 individual model pages.

Kind regards,
