Finding old-style phenolic board?
« on: June 12, 2017, 11:31:32 am »
I was cleaning out some garage space and found what looked like phenolic board, touched it and sure enough that's what it was, since I've handled plenty of it for small electronic projects. Not the phenolic pressed wood but the actual kind like this:

However, there was a number of interesting things about this board. The holes were GIANT and they were diagonally spaced. I've seen this kind of board before in very old pictures of TV electronics, bound to the back of such a large-style board with holes and no copper cladding.

I've been running around the internet for a while trying to find any of this stuff and can't seem to source it. I've tried combinations of phenolic perfboard no copper dark brown and so on and so on and nothing hits to the stuff I want. I've even tried searching by vintage TV circuit boards, etc, but not luck.

I know, I swear, that I have seen this kind of staggered hole form phenolic 'electronic' board, NOT phenolic pressed wood, with giant holes, used as vintage or possibly vintage+DIY TV/radio 'perfboard'.

I just can't find anything like what I saw.

A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Yes that's the kind exactly, only with bigger holes from what I remember, large enough to stick even the thickest leads through. Thanks. Im guessing now its called vectorboard.

It's called perf board if it has holes but no copper. Vector board has copper pads and the name came from a company named Vector that originally produced prototype/experimenting type boards. The name stuck, kinda like "Visegrip".
