Re: Tannoy Reveal 6D
Could be a few things.
Don't forget the DIL switches as they can go intermittent. Just flicking them up and down a few times seems to clear them for a while. (At least a year in my case).

All been discussed here previously.

Re: LG HT33S - Loud High Pitch Tone
Silly me,
I should have played the youtube sound in your first post.
It's definitely not a failing PSU noise as this was due to the oscillator whining. In your case you have some audio tone being...

Re: LG HT33S - Loud High Pitch Tone

Re: Vox mini 3 amp
That is the most common fault (so far), sound OK out of the phone jack but not the speaker. Most amps derive the headphone output from the main output device but these don't.
I've only ever seen one...

Re: Vox mini 3 amp
Hi Piwi,
I assume that was the last lot sold on Ebay?
I was watching it but didn't bid. Still you've got a good deal there I think.
