I recently purchased a 2284 concert telefunkem an antique shop, did a little restoration and is already working. But there's a problem, which is as follows. In order to be working some minutes, maybe 5 to 10 minutes, the audio quality will be lost, and begins to distort as much as we increase the volume and the lower it is without quality. It replaces each capacitor in the circuit that is one of the valves ecl86 because they were damaged as a resistance. Do the valves are tired? This symptom is noted in both FM and AM. I ask for help for this machine to work 100%.

Comprei recentemente um telefunkem concerto 2284 numa loja de antiguidades, fiz um pequeno restauro e já se encontra a trabalhar. Mas tem um problema, que é o seguinte. Ao fim de estar a trabalhar ums minutos, talvez 5 a 10 minutos, a qualidade do audio vai-se perdendo, começa a distorcer e por mais que se aumente o volume mais baixo ele fica e sem qualidade. Já substitui uns condensadores que estão no circuito de uma das valvulas ecl86, pois estavam avariados assim como uma resistencia. Será que as valvulas estão cansadas? Este sintoma nota-se tanto em FM como em AM. Peço ajuda para por esta maquina a trabalhar a 100%.
Cumprimentos
