LM4870 Noob mess up

[littlerick]

Sweet just tried lefthand side amplifier and I'm getting 29.3v DC at the board... More impotantly No flashing lights or frazzling sounds.

On with testing righthand side and see if I'm as lucky. If so I will solder the rest together n break out the CD player and test outputs.

Woo hoo... working all the way to speakers..... I'm a happy man!

Thanks Peter for a great kit and the oppertunity to have a go.

Thanks to all who helped with advice along the way... I'm off to listen to some AC/DC... See ya all soon!

Good stuff With no signal in you shouldn't have anything hot either... the chips should not be hot, perhaps slightly warm.

BTW, where did you get the case you used, and how much did it cost?

[littlerick]

Case was from here.. About £57 delivered

Now sit back and enjoy, happy with the sound?

I went from being amazed it made sound, to amazed at the sound it made with my first chipamp.

Ah I suspected it was a Modu case.. nice to know what the price is though from an actual purchase

[littlerick]

I must say the case for its price is wicked.. It is one of the cheaper models, but the 10mm front panel makes it look nice.

As for the sound... Got my 3 year old grandson, yes grandson.. in the room next door asleep. Very inconsiderate of the little bugga eh.

Let you know the sound side tomoro.

Thanks again for help n advice.

The multi meter will do this if it is set to mesure current . It was mentioned earlier in the thread about sparks when taking a mesurement.
