Re: Vox mini 3 amp

Hi Eduard,

That doesn't sound like the daughterboard will help you. The output to the headphones comes before the amp output so you would need to delve further back in the circuit.
As there are...

Kustom Sienna 16W

Just had one of these acoustic amps in with the symptom of blowing fuses. There's no info on these on the web so I was hoping it was going to be a fairly generic design.
Luckily it was, TDA 2050 as...

Fender passport 300 pro

Just had this one on the bench which was blowing mains fuses. Couldn't find any tech info on line for this model so I was hoping it was going to be something simple on the mains side.

Re: Tannoy Reveal 6D

Yep, those screws can be tricky and the transformer has to be removed too. A good fitting screwdriver bit is essential and I suspect an impact driver may have been useful too although I don't posses...

Re: Tannoy Reveal 6D

It wasn't me that made the PCB so I don't have any PCB layout info. See a few posts back for the link to the guy who made his own.

Re: Need glue to fix broken outer casing of Supra-Aural JBL headphones

Is this stuff the same (or similar) to plastic waste pipe cement? You can buy a fairly large pot cheaper.

Re: Tannoy Reveal 6D

Hi Don,

Glad you've got them OK. It's always good to have a look at the diagrams.
Well done for fixing it, why don't you let everyone know what you did as I'm sure there will be lots of interest.

Re: Vox mini 3 amp

Hi,

If there's no output from the speaker and the headphone output is OK then it's more than likely the output chip has blown. If you read the whole thread it mentions how to test the resistance...

Re: AOC tft22w90ps intermittently turns off.

There's quite a few vids on Youtube on opening monitor cases. One trick is to use a credit card to open the plastic clips. Easier to see someone doing it than to explain.

Good luck

Re: Help for mixing console BEHRINGER UB2442FX-pro

These chips are...

Gosh, is it 3 years already!!

To have the boards made would add too much to the price and although it would save a lot of time, being retired I've got plenty of that. I'm not sure how many I've...

Re: Asus VW22* monitor

That's interesting, I hadn't tried running mine without the ribbon connected. Will try that later and see what results I get.
