Hi, Finally today i rechecked i cleaned some contacts in the back of the board and ...WORKS!!! now i get clean sound! Thx for your help and tips .
Regards!
Finally i get in my garbage hehe some Nps capacitors. I installed, move the area sound to the RF zone, but same result noise.. Only in this area i get more volumen.
Regards!
Hi, question .. I start to replace capacitor but i found a area without polarity, this ones ar NP capacitor. Can replace this ones with polarized caps with same or better UF and V?
Thx!!
C100, C102 and C103
Sound good, i thinked the transistor is the 3 ones 2N3906 near of the area of sound. But you mention germanium style, i think i a bit confused .. Regards!
The floating cable from sophia card is only a test cable for the first try for connect audio from there to pin1 of db9 and rca to monitor, but this one is disconnected.
Hi , for doing a clean test i removed sophia card, and the trouble still continue. Noise continue, the cable distribution to rca is red to ground (case of rca plug) and blue to + (pig of rca).
Regards!
Hi , the red one is using to ground , i use multimeter and not contacting anything more. The blue one is + , i tested with multimeter to rca connector and all is fine. Ground to Ground and + to +,
Regards
