my t-amp experience

Thanks lostcause,
C12 & C11 are both goners they are [were] on the underside of the tripath chip, I suspect the soldering iron has done a lot of hidden damage too!...actually I think it's all beyond me so i'm ordering a 2020 kit from AUTOCOSTRUIRE it's 80 euros [are they fast deliverers?]
cheers

Crikey, sounds like you've dived in with both feet! Don't give up hope yet though it's a tough little chip/board and those SMD's take some hammer. You can get replacement parts (if you have damaged any) from many sources. A lot cheaper than EUR80!
What about the AMP6 instead? I'm contemplating one as my next project.

What another one!
thanks LC I'll check that out now

Difficult to tell, but it just looks like it's buried in the solder.
Should be able to dig it out and re-solder. Use tweasers to lift it off whilst applying some heat.
You can get a replacement from a multitude of places if you think it's toast. Seems a pity to bin it just for that?

nah! it disintegrated and flew off into the wild blue yonder...LC could you tell me what the rplacement caps look like? what would the markings be on them? would the spec be critical?
are they little disc types or what?
cheers

C11 is it's brother. They both decouple the power supply directly to the the respective left and right supply pins. I think it's an 0805 SMD (refers to its size) and has a value of 0.1uf but I'm not sure that will be marked on a cap that small. It needs to be as close to the pins as possible to reduce overshoot that's why they use SMD's. You can get a replacement easily and then replace C10 with a better one with a higher value (optional, but worth it). There is what seems to be an SMD in your bag but you need to know the value and without the kit you'll have no idea. They are damn cheap so pop into your nearest RS counter for one...or two...get a bag of em! Unless someone on the forum has a few they can send to you...ask in the marketplace....sorry I have a **** load of other stuff but not them. Pity because I work in Prescot and could have dropped some off!
