Hello!
I realise that noone has posted here for quite some time, but I have a question:
If I export my layout as a graphic image at 1000 dpi the exported image goes out of scale. How can I get the picture in scale whit the components size so I could etch the layout?

Hi, could you tell me where to find the specific symbol for the PNP Ge transistors used, with the arrow pointing TOWARDS the emitter on the lower side?

also, if you don’t mind, how do you add the text to the board that will be etched in the copper. thanks! and sorry for all the questions, i am a noob.

Thanks for the wonderful tutorials! The ground pour one was amazing. I’m just wondering how you got the perfboard layout (all black on the white background). Thanks again!

Well, trial and errors…
I followed the PNP circuitry and attached to the 1590B wiring diagram… used 3DPT and a pair of vintage germanium transistors…

Nothing turned on, no LED, and no sounds…
Back to the drawing board again

Paul,
Many thanks for the link (wiring up 1590B), your in incredible images and top notch instructions are much appreciated!

David, Please check my article called Wiring up a 1590B and see if that is what you need. All the best!

Thank you so much for the easly to follow PNP circuitry!
However, there is no further instructions to isntall 3DPT, Jacks, LED to this cirtuitry.
So, at this point I and at a stop.
Any further instructions or suggestions is greatly apprecitated
David
