The XTC module schematic is not in Soulinsane's all boards.zip

I would love to get that one. Does anyone have it?

Thanks

I have proofed my own set of schematics for the RM100, SL+, Ultra XL, and Clean modules so please use them for your personal reference and learning. Like I said, this is my own work and it has taken me many hours to go through the whole amp and trace it out so give credit where credit is due. Basically, don't steal this work and sell it on Ebay lol. Its free to everyone. The voltages are approximates values and are referenced from an older set of incorrect schematics. I have yet to measure the absolute voltage values, but that will be the next thing I do. Once done I'll post a revision.

Use this to learn about you RM100 and how it operates. Its really a wonderful design. If you use it to modify your RM100 then do so with care. I take no responsibility for what you do to your amp and modules. Its also important to note that there are voltages of over 500VDC inside this amp even when unplugged. If you touch something the wrong way it can kill you or in the best case destroy your amp.

These schematics are .cap files. You will need to download and use CAP CAD in order to open them. Its a free 2D cad program that will allow you to zoom, modify, and change these schematics. Everything presented here is stock, but there may be some component values that differ depending on when your amp or modules were built.

All boards are in this Zip file http://www.mediafire.com/?0jvddjytjdy

If anyone finds anything wrong or wants to add modules to this work then feel free to do so. That's the reason I am sharing it. I have went over everything at least 5 times and it all seems correct.

Here is a screen shot. Everyone enjoy :D

Note share schematics? Why? Virtually every other amp maker out there including Mesa Boogie makes their schematics available to the public. Considering the issues that seem to follow RM-100 it would be very helpful to have them available publicly - at the very least schematics for the power supply and output section should be published. This is where most of the problems seem to happen. Countless blown fuses . . . . Having individual bias on the rear panel is a blessing which is nearly wiped out by having to constantly open up the amp to change fuses .. . . . which could have been placed on the rear panel for quick access - like they are for most other amps. Get rid of the redundant FX loops and you would have room.

capdraw is no more... what a sad format.

I have tried for hours to open the files... if someone could please post the schematic in pdf format I would be in debt.

I cannt seem to attach documents in a post.. but I have a whole bunch of RM100 and module schematic's .. some have been very recently traced by Joey from SLOCloneforums and (I think) I did the recto.
