Hi Miguel, Espero que estes bien. Muchos saludos. I am very pushed for time at the moment so will tell you more details about the Astrad later. I will need your advice on a few points. The audio is working fine now but I discovered the middle ferrite aerial coil is disconnected. That is one obvious problem. I will need to resolder the winding. I am not yet sure where the original connections were but will investigate. The power capacitors are a sort of grey colour and the transistors "top hat" type. These radios were built in Riga where I have lived. Mine has 1969 on the speaker so would have been exported as the Astrad in the Brezhnev era.
I am also working on an East German GDR valve radio 1964 you would find interesting as it's a mix of German engineering and maybe a bit Soviet too. This has valves ECH81, EBF89, EABC80 and ECC85. This latter is printed circuit mounted and I am studying the schematic before I do any involved work on it.
