Hello Hugo
Can you please give more informations? I think, something's wrong here. The ECC81 was rarely used in table top / console radios but quite often in car radios, tv's and amplifiers. No radio schematic of Nordmende that i have, shows a configuration using the ECC81. The Caruso 58 chassis i have has the tube line up ECC85, ECH81, EF85, EABC80, EM84, EL84 and selenium rectifier. The schematic of another Parsifal/Caruso shows a tube line up ECC85, ECH81, EF89, EABC80, EBC81, EM84, 2 x EL84 and selenium rectifier. If you think, this is the same as yours, i will mail you the schematic (> 1 MB)
