Powering LEDS

Would I be able to trace back from my LEDS in my amp (solid state btw) to find the transformer that powers them inorder to hook up an LED strip?

I haven't been able to find any info other than people using external power sorces

What is the amp? The LEDs won't have their own transformer (typically), and certainly won't be powered directly from the transformer. They will be powered by a filtered (and possibly regulated) power supply that may be shared by a couple of other circuits.

With the particular amp information, I can give you a more specific answer.

I'm not to keep on amp design and the only info I could find was people saying you needed a seperate transformer to output 12v or 9v.

The amp is a B-52 Ls-100.

I haven't been able to find a schematic but I can take some gut shots if that would help.

There will probably be no need to get a separate transformer, and in all likelihood these people are merely repeating what they heard from someone else.

Gut shots would definitely help. I don't have a schematic for any B52s, and haven't dealt with ETI Sound Systems. So, I don't know how easily I could get one.

Alright, I'll try to get some up tomorrow.
I'm just going to try and send them an email also.

Hey, I've got the schematic but I can't post it on here.
Can you pm me your email?

Slap on a high value resistor you can power LEDs from line voltage AC if its in no 'no human hand will ever get near' enviroment.

The secondary winding of the transformer in a solid state amp would probably be between 20VAC and 50VAC. Steal the voltage from the secondary side of the bridge rectifier. No need to bother with voltage regulation for LEDs. Wire your LEDs in series, work out the total voltage drop, slap in a resistor to limit the current (it might have to be 1/2watt or 1watt power rating).
