Kir_For_Pleasure · Jan 24, 2008

Have taking a photo of my SSL card, up for trubleshooting.
Maybe you see something wrong ?
i built it for about 3 years ago, tryed it then and it worked.
now when i try, it smelles warm and it dosent work ??
i have new opams and metering the vaule of the resistors searching after bad solderings....

You can always start to remove all IC:s and such and make sure that all supplying voltages are correct. Besides, this is the first thing to check in any circuits before mounting anything in the sockets.

now everything looks ok. measured +14.97 -14.97 and 12V :grin:
tomorrow i try it with audio.

stupid question, but why do you have the resistors like that?
you should be able to bend the leads and them fit flush and clean right into the pcb.

it looks like he de-soldered one leg on all of them.

i think your right. on a couple it looked like he had them vertical like when you dont have enough room on an opamp.

yes one leg of the resistors are de-soldered. Pepe you must have the opamps in when you measure for correct voltage value, now i have pass audio thrue and i have audio on both of the outputs. I hook up a cd player and listen in a hifiamp so the sound wasent so funny to listen to =) but it sounds :grin: and nothing getting warm.

Please use the dedicated help thread (to make it easier to search in the future, so we don't have to answer the same question again and again):
