Framus Cobra PCB

Hey, I am looking for a pictures of Framus Cobra PCB.
Mainly the down side of the PCB, does anyone have some?

Willing to pay for quality photos of PCB's from both sides!!!

Framus is the only high end manufacturer that is so comfrtable with letting not only the schematics but the PCB drawings as well, They even have all the versions too! Enjoy

there are no wires on the PCB's just layout of components...

Hell, Thats enough info to reverse engineer the amp! I have tuned up these amps and they are monsters, I LOVE the cobra!!!, what are you looking for specifically, maybe I can help you.

actually it is not that easy to reverse engineer the PCB :P I have tryed it and failed, if you do it your own way you might get some serious unwanted hum or some squeeky noises just because of the capacities between the routes on a PCB. I am looking for an original photos of PCB so I can make it by my self :P I want to build the whole amp, I have already successfully built Soldano SLO100 clone and I think It's time for something more advanced now

You need to be more careful about it then

It's a valve amp, it's crude and simple, layout isn't terribly crucial - the drawing of the component layout should be plenty to make a PCB from.

In what way did you 'fail'?.

IMHO there is not a whole lot of Voodoo magic in the layout of there PCB's, looked pretty standard layout. You can copy the part placement almost exact. I have worked on these amps before. If I can get hold of one I will take plenty of pics. I have as well started down the path of copying this circuit, although I combined the preamp and power amp on one PCB with the controls and EQ off the PCB. Lost the files when my daughter used my laptop and crashed it. Anyway in my opinion you can take the schematic, load in the appropriate components and layout a PCB and get good results. It depends on how savy and experienced you are a t laying out a PCB!!! Another thing, unless you or someone you know is a software/firmware engineer, you will not be able to copy the MIDI switching! Programmed part there. Good luck!

This was what I was working on, based on the Cobra.
