Hola amigos:

                  Tengo un receptor Philips 291A pero lamentablemente debo cambiaar el capacitor variable y es de un tipo especial, como si fuesen trimeers de aire concentricos gigantes, por ejemplificarlo de alguna manera. Por tal motivo es imposible reemplazarlo por un capacitor variable estandar.. Si alguien sabe donde se podria conseguir un capacitor de ese tipo (triple de 500 pf por seccion) les ruego me escriban.. 

                  Es un excelente receptor y no me gustaria tener que hacer "injertos".-

Gracias 

Heriberto

Dear Members,

I purchased a Philips 291A export model in 2005 and someone removed the variable capacitor.

It is a very special sealed three gang cap. 12 to 500 uuF X 3

According the original Philips Service Documentation the part number is 49 000 05.0

During the last two years I have searched by this scarce part to restore my model.

I will be very thanked for some help.

Thanks in advance, Bruno.
