I took the radio back today and the guy replaced 5 electrolytic capacitors, two disc-like one, the IC01 circuit and a transistor. The capacitors he replaced had current problems. He explained to me that he attempted to tune the IF several times, but got different an incisistant readings and low volume, which finally narrowefmd down to these IF transformers. Also, he suggested that all three FM-involved Ts be replaced as there may have been corrosion inside or other process that may have damaged the tiny coil(s) inside or the ferrite core. Now, since I don't know the previous history of the radio, it actually may have been exposed to almost anything for all I know. The inside of the casing was mostly dusty when I first opened it, but there were areas like some brownish liquid got inside and got crusty, plus some of the electrolyte that had leaked under the 16V1000uF cap.
I'm glad if you find all this amusing, but I don't know anymore. It has been left for me to try and find these little transformers and give the repair a final shot, but I am running out of options here, guys. The only noticable improvement is that the radio secton works and that you guys solved the voltage problem. The volume is still bad.
So, please, if the printed markings on the three removed transformers, the brand and the top colour mean anything to you and you can tell their values out of it, I beg of you, do let me know. I have been trying really hard to save this radio, but the scrap box starts to feel ever so near. 😔
