I'm starting a drawing for diy mod purposes. I want to keep track of the mods I start doing by logging them on a PCB layout within Diptrace.

Currently I have a few schematics in the program and I'm working out how to place things where they belong, reading the tutorials, etc.

I really just want to start with a drawn MTS pcb and go from there, swap out the components that I've modified, change things that I think might work and bounce them off a few folks. Total DIY, screw up my own module type thing.

If anyone has a drawn PCB they wouldn't mind sharing to get me started I would welcome your input.

Could be good fun and something new for me to learn

I haven't drawn any MTS PCBs because they vary so much. I have done schematics for all of the modules I've modified using Eeschema. Take a look here for an example done for the Brahma module. PM me and I'll send you a file to.get you started.

Thanks, CrunchBunch. I do have a british schematic in the program. Was just hoping to find a base drawing for the board itself to start placing everything where is goes in space, layout form.

Just to get a visual to keep track of

I appreciate your help

I have started something, but it's far from finished. Maybe you can reuse some components i created:

The width of the board is not correct, i need to fix it (and a lot of other stuff).

Also did a tube board (untested) 1 layer and 2 layers:

Regarding the two voltage regulators in there. Why is the 7812 feeding the 7805? Wouldn't it be better to have Vcc feeding each directly? Also, what is the progress on a new board design. I'd love to get a blank one just to "play". Cheers, Lucius

If you feed the 5V regulator off of 18V it will have to dissipate a lot more power, so you would probably need a heatsink.
