BC 348 segnale debole
Gabriele Seccia

Salve ho acquistato questo BC 348 ma purtroppo noto un'assenza di segnale pur sentendo il fruscio della radio frequenza .

Solo se appoggio il filo d'antenna sulla griglia della VT70 o della VT86 ascolto l'emittente ( sulla 86 il volume e' decisamente piu forte) , il fatto e' che riesco ad ascoltare solo una stazione , pur ruotando la manopola di sintonia .

Mi vien da pensare a un guasto allo stadio Convertitore . Vorrei avere altri pareri in merito

Saluti Gabriele

Da un ulteriore controllo ho notato che ho una tensione positiva sul Cap della VT93 di 8V. e mi manca tensione sul piedino 4 ( Placca del triodo ) della VT 70
