Convert schematic to layout
« on: March 01, 2022, 09:50:07 pm »
How are you all able to visualize laying out an organized board when looking at a layout?  I am trying to develop my skill set to build boards from a proven schematic. How are you all able to go from schematic to proper and logical organization of a turret/eyelet board?Any help is greatly appreciated

K.I.S.S.  Don't re-invent wheels.

Find the older Fender with a very similar plan and copy the layout as close as you can.

Yours is the AA-Champ with an extra triode in the middle. (Things like 6V6/EL84 and strange cathode resistors hardly affect layout.) You will have to decide if the "extra" is on the first or second twin-triode, but then it is just stutter-and-stitch.

Did you see a tip Sluckey gave recently? "I spend more time in Visio than on the bench." He has and knows Visio; you know Leo had pencil and paper, and that worked for me too. Pencil WITH ERASER.

Thank you for that. That's really helpful. I'll look in the library for that associated schematic and sharpen my pencil!

+1 on what PRR said.

From my own experience, two bits of advice:    Start with pieces of the circuit rather than try to do the whole thing at once, which is difficult to visualize.   And, Doug Hoffman's boards are beautifully laid out and very efficient -- I'd copy some of his conventions.

I don't have Visio (wish I did), but as I've gotten better at using DIYLC, it can be a reasonable (if sometimes maddening) tool to use.

That's kinda how it started for me. I can work my way through the power supply effectively but once I get to the preamp, PI, or tone stack I begin to wonder.

In addition to Doug's layouts, I've used Sluckey's layouts too.  Highly recommend you check out his different schematics/layouts on his website.

His website along with RobRobs's are my first stops when starting a new build
