I don't know if he is a troll, so I won't call names. He is very unfocussed and asks too many questions (he says he is a 13 year old kid). Most have given up on him including myself. He needs to go learn instead of asking questions so often. He needs to get his 12v chip amps working right before even thinking about discrete jobs with 190 volt rail to rail voltages!

Well, either he is a troll *or* he's a 13 y.o. guy working *very* dangerously and ignoring safety suggestions.

SWITCH OFF AND UNPLUG IT FROM MAINS!!

TAKE the foil off the transformer - it is not needed and dangerous you are close to creating a shorted turn with the transformer top plate and base. Please remove ALL silver foil.......

Forgive me for asking but are you * OLD ENOUGH * to be working on mains?

If not you must have a suitably qualified person supervising and check your work before plugging in!

I give out information on these boards on the assumption anyone following them is suitably qualified and competent in electronics.

Im 13 but i have been woking with 220v since i wad 9 so im very experienced
In *any* case, whether he's a troll laughing at us or he's *really* a 13 y.o. irresponsible kid working with dangerous stuff, the conclusion is the same: don't touch him even with thick gloves.

the tdaa 2003 didnt work so out of frustration i killed that tda1517 with 200v from caps and it blew up into pieces,wow,very fun,im going to this to the lm1875 t s since i hate them so much since theyre crappy sounding.And costed as much as an stk 50w x2 chip. So i will kill them and burn the trafo and smash the case and then throw them all in the fire.
Chip amps are very problematic and not worth.Im going build transistor amps since theyre easier to build and cheaper
And build homemade smpsus since trafos are to expensive

THANKS for the confirmation that you are not a 13 y.o. experimenter but a very sick grown up guy, who fakes being a kid to get our attention.

You are desperate for attention, even negative.

What will you say next?

Why did I call you troll?

Well, maybe the Wiki description fits you like a glove:
Quote:
Troll (Internet)
From Wikipedia, the free encyclopedia

In Internet slang, a troll (pron.: /ˈtroʊl/, /ˈtrɒl/) is someone who posts inflammatory,[1] extraneous, or off-topic messages in an online community, such as a forum, chat room, or blog, with the primary intent of provoking readers into an emotional response[2] or of otherwise disrupting normal on-topic discussion.[3]
or, from the Urban Dictionary:
Quote:
1. troll

One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument

Not entireley sure about "troll" but certainly a kid (or mental equivalent) who's outbursts of rudeness and demands got even the better of my giving nature.....
From the above responses, clearly not a person of engineering calibre with a temper like that!

just saw an old project i made called the relay amp,
It was an amp with 3 relays one at 24v on at 12 and one at 5.
Each rellay was triggered at a different voltage and made up a horrible sounding but very powerful amp.
I this worth Souping up with 200-300 relays or low rds mosfets each at different voltage,will it sound harsh or not?
