Most layouts that have this modification made specify it some way or another.

You can always make any transistor fit a layout. you just need to carefully twist the legs around each other using a pair of needle nosed pliers. It's not pretty, and it's not an ideal solution, but it works.

ALWAYS check the pinouts, especially on un-verified layouts. There are layouts on the main page that name the original transistors, but are orientated to use more common replacements. Using the originals (should you be able to find them), will involve leg twisting!

by way of a pictorial reference to follow up on this for anyone who hasn't come across the idea of leg twisting, here is leg twisting in action...

the layout i wanted to make was designed to take vintage 2sc828 transistors, which have the pinout (facing the flat side with legs down) as ECB (emitter, collector, base).

i wanted to replace these with modern equivalents 2n3904 which have the pinouts EBC (emitter, base, collector).

from knowing the pinouts (available from the datasheet, just google) you will realise that you need to swap the last two legs around (the collector and base) while the emitter will stay the same (as it is the first leg for both).

when you twist the last two legs and put them into the circuit (using sockets here) they will looks like this...

covering the bare metal legs with scraps of insulation from some other wire will ensure that they don't make contact and short themselves out.

hi mate!
i just saw your post.

i'm very happy you've build it and that it works!

this layout was one of the early once that i drew so i wasn't sure about how much information i should put in the picture. i just wrote "doublecheck the transistors orientation"
i now understand i should write pinouts too. sorry for that.

i've run into the very same "problem" with a build i can't remember from the main site 2 years ago so i know how it feels...when you solve it! it was great!
sidenote:i know it sounds crazy but...
i miss debugging...
