The link was there but it broke off. I just saw the metal part that you solder in the pcb holes. If I was looking to see why my board isn't turning on but it is getting power, what should I start looking for? Something near the power connection? And what?

Hey guys, I tested the output from the transformer and found voltage. I can't remember how much but it did shock me lol. I will post a link with the correct preamp schematic. (the other one was the wrong model) Anyways there are zero ohm resistors on the preamp board ( it calls them zero links on the schematic) and there was one missing where it is printed on the board saying stereo. So I just put a wire there since that's basically what those resistors are since they have no resistance but still no luck. If I need to explain better let me know, thanks for all the help for a newbie.
Here is the link.

Sorry about being unclear, auto correct kills me. I'm testing them in a few.

I can't find ic11 or 12. I found ic1 - 9 though. The only bad coonections I found were the ones to the speaker out, but it doesn't explain why my preamp board is getting power. I tested the power connected to the pre amp board but it's not picking up any voltage.

I couldn't find the exact schematic but I found one close. I measured to see if I'm getting power to my preamp board and I'm not, the connector to the preamp is coming from the transformer. Any suggestions?

Trace Elliot gp12 Smx..... The model number is 122hsmx. I'll try to find a schematic.

My amp is getting power, I can see the fan turn on by the transistors but I'm not getting power to the board with the input and potentiometers are. I'm thinking it's the power connection to that board. What should i look for with a multimeter and so on. Thanks
