 Re: The workbench thread I meant the schematic, but then i went back and found it a couple pages back.

Re: The workbench thread So the PI doesnt work properly because the useless twat I bought me components on has given my 820R resistors rather than 82K resistors. This probably explains why one side of the PI can produce 35Vpp and the other side only 0.7Vpp. Fucks sake.
Yeah I know I should check the component values first but you'd expect them to be right...

Re: The workbench thread Ah! Yes, that would be a problem. Well, it is good that you figured it out. I haven't had any sort of issue like that so i didn't have much to suggest. I am pretty compulsive about quadruple checking values throughout the building process though. Though it is not really a big deal, i haaaaate unsoldering things once they are in.

Re: The workbench thread There are other things wrong too but at least when I put a sine wave into the PI I get a sine wave out of the speakers rather than half a sine wave  I should probably build a dummy load box so I can look at the output waveform.

Re: The workbench thread Rackmount Compressor?
That thing is sexy looking though.

Re: The workbench thread Looks cheeky whatever it is. I have the bits on order to build the aforementioned dummy load so I can work out what I fucked up

Re: The workbench thread Bits for the dummy load are here. Gonna get that mother strapped together tomorrow. Nothing too fancy - just a 50W 15R aluminium clad resistor in a box with a BNC connector.

Re: The workbench thread Is the "Dummy Load" some kind of stencil or sticker? Did the box come that way or did you do that some how?

Re: The workbench thread I used a thermal label printer. If you put enough clearcoat on top you cant see the edges of the label. I didnt bother here though.

Re: The workbench thread Ha! I'm getting one half of the waveform on the output. Time to look into the power amp to see what I've fucked up
