Old brown PCBs

    I'm wondering, is it possible to obtain those old-school brown PCB kits
    which were in use before fiberglass became the standard for PCBs? You
    know, the stuff that stinks a whole lot when on fire. :)

    I'm about to build a few "retro" circuits using a etchant-resistive pen
    method, and an old-school brown PCB would've been an incredibly nice touch!

    Search e-bay for 'pertinax' ?

    'Pertinax' is probably a brand name... it's just phenolic.

  4. That stuff was junk when it was common, even to make something look "original"
    I think you'd be making a mistake using it.

    Synthetic-Resin-Bonded Paper or SRBP.

    Trade name is "Paxolin"

    Thanks, I'll try to get my hands on this stuff. DIY stores in my area
    don't seem to have anything but fiberglass, though.

    Sorry for the confusion - what I was looking for is the trade name of
    the aforementioned stuff. I'm sick and tired of spending hours sprawled
    over the drill, making holes in fiberglass boards...
    I'll stick with pertinax, and draw all the traces by hand. Not only that
    I lack the equipment to do it the modern way, but a CAD program wouldn't
    allow me to draw those wavy traces I'm aiming for. Also, photoresistive
    boards somehow cost six times more than "ordinary" ones in my place - I
    guess that's the price of living in a countryside!

    Guess pertinax will do, since I'm building a fairly simple (yet high
    voltage) circuit - hope the tracks don't lift upon soldering!
