Question on a dynaco amp
« on: August 12, 2011, 03:30:47 PM »
Hey guys, I was wondering if anyone had any idea where i can find the artwork for a dynaco mark 3 60watt power amp. I saw they sell the pcbs on ebay, but I'm currently living in argentina and don't want to pay for the shipping and custom charges so i figured ill make my own :icon_biggrin: Sorry to change the subject guys i know its a pedal forum but i didn't know where else to start.

Triode Electronics has a lot of info and parts related to Dynaco products. I assume you're looking for a schematic?

I actually have the original dynaco manuel with the schematic it was my fathers back from the 70s i think. The only thing i need is the pcb. What i need the the artwork of the pcb so i can etch my own down here in argentina so i dont have to pay for the insane shpping prices and custom charges in argentina. Thanks for the links though good to have!

This one has some sketchy PCB artwork that they indicate applies to the Mark 3 driver board. You'd want to clean the artwork up some with a program like Inkscape before using it to create any boards.

AWSOME!! Great stuff!! I'm not to good with programs like those. Is it very difficult to do, are there any tutorials on how to go about doing it? Thanks again man i appreciate it.

Seems i need those tutorials too! Opened the pdf in Inkscape but haven't figured out how to go about modifying it.

There is still the old school method of printing it out and then modifying the printout with white paint and black paint/marker,  then scanning it back into the computer after the cleanup. Once back in the computer you can resize it there.

> have the original dynaco manuel with the schematic

The pictoral shows all the traces on the PCB. There's hardly a dozen. They don't do anything tight or tricky. You could PCB-mask it with a Sharpie. Or you could just poke holes then wire the leads directly to each other. It really is that simple.

yeah that's great idea to, but now that i have the artwork already done I'm gonna try fixing it up with white out. If that ends up being a failure Ill give the other options a shoot. Thanks for the help guys!
