vintage Telefunken 884V radio, circa 1952

[Dr Lime]

I have a Telefunken Model "884V / UKV Concertino-Sekretar" as shown here:

It is my understanding that this is a special edition 50th anniversary model released in 1952, although I have seen some indication this model may have been released in other (prior?) years. Mine has a customized Telefunken logo badge indicating the 50th anniversary edition.

I am looking for schematics, repair manuals, and any further information about exactly what I have.

If I cannot find these, information about similar models from the same time period may prove useful.

I am attempting to repair the power supply section, and am uncertain of the value and function of several components.

Anyone who is familiar with the Telefunken power supply designs of this period may also be able to provide useful information.

Do you have any reference to this model (or similar models) in any Rider's publications, or other sources?

Can you direct me to other people who may be able to help?

Thank you for your time and consideration.
