    FM is working again. I repaired L111 which was faulty. I measured p-y and I have between 11 and 13v maximum. It's too low, as I should have 22v. I will continue investigating. Thanks, Stéphane

    Hello! All my excuses for not giving enough details. Yes I replaced c308 but also c719/c723 (motor caps). And also c709. I did a number of steps, including injecting 10,7 mhz on the ech81 grid and the eye is wide open. Meaning problem is located before (in the FM tuner most probably). Can someone tell me the value of L111 ? Thanks for any help! Stéphane

    Hello all, This stunning radio is working fine excepted the automatic tuning. I have tested voltage between test points P and Y and with a strong station I get max 2v while I should get 22v. 2v is not enough that's why automatic tuning does not stop on stations. Ecl80, eabc80 and ebf89 have been tested and are all good. Ecl80 and eabc80 polarization voltages are also correct. Do you have an idea what could be the cause of this problem ? Thanks for your help ! Stéphane
