Ultra Troubadour U7961 ... quiet as a mouse

Hi Mark,

Thank you, glad to be here

Here's my recently acquired Roberts RT1

The UT is not quiet anymore after I pulled off the control knobs on the front and had a bit of an investigation.

   

Although it's not very melodic

I couldn't get any continuity across the Live input on the on/off switch, the Neutral was fine so I jumpered (soldered) a wire across (just to get it going).

It still didn't spark into life though  but after a bit of voltage probing around the big green resistor I thought I'd move the input voltage selector, it too pulls off and then you simply twist it around to the desired voltage input range and press it back in again.

   

Hey presto, lights, buzzing and stuff

Then the big yellow capacitor started to melt !! Power off !!!!

   

So to cut a long story short the UT powers on now, not a bad start, it doesn't tune into any radio stations, although it does make that noise that radios makes as it is about to start tuning into a channel, woo, woo, for want of a better descrition every now and again and I need to find a replacement capacitor.

Any ideas?

   

Cheers,

Martin
