Crackling Sound from 1969 Suitcase Top
« on: April 09, 2020, 04:00:18 AM »
I have a suitcase top and a Vintage Vibe 4 pin power supply which has worked fine cup until recently.

It now exhibits a crackling sound (mp3 attached takes a few seconds to come in) There is also some slight distortion and lower level coming from the left channel when playing the piano.

Anyone any ideas what this might be and how to fix?

Many thanks

Oliver

It almost sounds like a flaky connection somewhere, but if it is inside the power supply, I would contact VV.

Thanks I will. I bought the item second hand so not sure if they'll be interested in covering it...

If they can't help, and you know how to solder, the next thing that
I would do is to reflow the solder on the board connections. It could just be a cold solder joint.
I doubt that any parts are bad.
