radiola: Radiola 549A restoration - tips wanted on first steps
William Smith

Dear members,

I have just joined radiomuseum.org and would like your advice getting started with the restoration of a Radiola 549A radio I bought recently.

First, I think it is identical (except for the grill) to the Philips 638 A, which is no surprise given the historical links between the Radiola and Philips companies. Is it safe then to assume it is OK to use 638 information such as the schematic posted for the Philips 638 here.

I do hope so because I found a detailed step by step restoration of the 638 described here (in French) which would be very useful.

Second, I plan to replace the capacitors. I can see their microfarad (and micromicrofarad) values in the schematic. But it's not clear to me what voltage rating they should be. A valve amp I built from a kit recently has capacitors with voltages ranging from 25V to 450V, so I am aware I need to be careful about this.

Lastly (for now) I can see one of the valves is broken as bits are rattling inside it. It's a E463 penthode, this one here.

I guess I can replace it with any of the ones marked as identical, right? Do you have any tips about buying valves? Like new versus used, ebay or known dealers or anything else?

Looking forward to your help

Best regards,

Will

Dear Will,

Model Radiola 549A uses the Philips 638A chassis, so for repair purposes you may use the documentation of the Philips 638A.

See table of equivalent Radiola and Philips types for the early years:

By the way, your link to the French site with the step by step restoration description does not work. You should end the link with html in stead of htm.

Regards,

Gidi

Dear Gidi,

Thank you for the information about the Philips 638A chassis and pointing out the non-working link which I have now corrected.

Regards,

Will

radiola: RA549A Skala Ausführung als Steckkarte
Manfred Rathgeb

Das ist mir erst jetzt aufgefallen, weil es beim Aus- und Einbau des Chassis irgendwo klemmte. Die Skala besteht aus zwei Teilen: Einem festen Rahmen mit nur den Wellenlängen (auf Bild 1 unten) und der einschiebbaren Karte mit den Stationsnamen (Bild 1 oben), die - weil nicht voll eingeschoben - die Ursache des Hängenbleibens  war. Dennoch durchdacht: Man kann die Karte von vorne herausziehen, ohne Eingriff in das Innere.

Wie sich die Bilder ähneln! Auch der PHILIPS Super Inductance 638 hatte so eine Wechselskala:

Mit zunehmender Vermarktung der Geräte im Ausland bestand wohl Interesse daran, sie mit einer dem jeweiligen Land angepassten Skala auszustatten.
