Yeah... he even suggested that the old capacitors may have been some kind of special series for radio/audio circuits and that the new ones could be of different internal resistance, affecting the signal strength. My other unit has Elna, Lelon and Rubycon caps inside, all rated at 85°C... I am still waiting to see what will come out of his diagnostics, at least he has all the necessary equipment at his disposal. That "something" bad is really a gold nugget I'm curious to find.
Searching in progress...
Please wait.Comment

He should have found it by now, if he got all the RF equipment he needs.

the guy is full of shit,
they didnt have high-spec electrolytics back then, and they arent used in the RF path anyway.
he just doesnt know what he's doing, he's probably used to fixing audio gear and not rf.

Hi forum members,
In the past i have had many helpful hints from generous forum members in diagnosing and solving issue related to most of my electrical things.
Fyi, i have been keeping this unit of Sony radio cassette player as the cassette belting has worn off but the radio has been working fine before. Recently, out of a sudden i found out i can't get any radio reception at all (no signal from FM,MW or SW band) except some buzzing warp noise from the speakers.
I opened the casing inside and checked for any dry solder, burned component or loose wires... -

I'm trying to fix a digital multimeter. It was working until I blew the fuse (actually the "buzz" for continuity wasn't working). I've now replaced the fuse but it's acting strangely. When I turn the dial to V, nothing happens. But when I turn to anything else, it makes a continuous, very fast clicking sound - like the piezo buzzer is trying to do something. And at each position of the dial (other than V) there are brief flashes of life on the LCD. It doesn't seem to matter if the probes are connected. I wasn't sure where to start, so I've tested most of the diodes and cleaned the... -
