    Blown amplifier part.

    The urge to put another fuse got the better of me. The unit turned on fine and lit up however after a second it cut out and the fuse blew again. I am assuming that this is due to the faulty capacitor?

    Blown amplifier part.

    Hi I’ve opened it and the glass fuse inside has blown.

    Blown amplifier part.

    Hi, I got the service booklet. Found this. The part it mentions towards the bottom which is mounted on the Mains transformer is the part which I’m focussing on. It says towards the middle about the fuse mounted on the back. There is a black screw type pod which sticks out of the back. It is...

    I guessed that. Like a fuse… when it comes in post ill report back if works Thanks a lot

    Blown amplifier part.

    After examining the capacitor and where abouts it’s situated in the amp. It’s not a noise suppression capacitor more a capacitor which deals with power. It said it’s a kind of safety capacitor - hence why it blew when the volume was turned up too fast… and it made a pop sound so would tie in...

    Blown amplifier part.

    Hi, I found one on the internet and I ordered it. It’s the same as the original… a new one tho. I saw that these ‘rifa’ capacitor have a habit of exploding - someone even stating… ‘the exploding capacitor…!’ I have tried wiring it up without the capacitor and to no surprise… it didn’t work. So...

    Blown amplifier part.

    Just taken that dodgy capacitor out. Did the multimeter again and it showed up as nothing… It’s dead for sure.

    Blown amplifier part.

    Sorry I got it wrong. When power off it measures 20 k ohms

    Blown amplifier part.

    I found these. The gold one looks similar but I’m not sure…? Thanks

    Blown amplifier part.

    Yes. The resistance is zero when no power is on. When I get time I’ll take the dodgy capacitor out and wire it without the dodgy capacitor. That’ll make the circuit complete as there’s obviously no power getting past that as the lights on the front are wired after that and they don’t light up...

    Blown amplifier part.

    I now strongly think that this is why my unit is showing no sign of life. I now think that when someone wazzed the volume up to fast it created a surge which blew it.

    Blown amplifier part.

    Hello. I put the multimeter on each end of the blown capacitor exposed wire part and it read nothing when the unit was turned off but when I turned it on it read around 20 k ohms. After further inspection… the capacitor is connected to a direct neutral wire coming straight from the mains. So...

    Blown amplifier part.

    Yes I’m struggling believe that the noise capacitor that’s gone would affect the whole power of the unit… although I cannot find a fuse… there has to be one somewhere…?

    Blown amplifier part.

    I’ll take it out and then try it without it to see. As the blown capacitor is connected to a major coil, I’m hoping that it has just blown and broken the circuit. If it works without it that means I need a replacement one. Thanks

    Blown amplifier part.

    Hi, does any one know what this component is which unfortunately has blown on this amplifier. It’s a 1980 Ferguson 3939 amplifier which someone in the past did something and it cut out fully. Upon opening it up I see this and It looks to be the issue. If anyone could tell me what I need...

    Marconi 4461 dial cord nightmare

    Hello, I’m currently in the process of repairing a 1976 Marconiphone 4461… I have un seized the turntable and done all the usual stuff with the rest. But… the dial cord has come off and for the life of me I have been sat for hours on end trying to put it on. It seems there is a specific way it...
