Up for sale here is this set of 2 new mini circuit boards.  You can use these to adapt SOT-25-5 SMD transistors to replace through-hole parts.  These are really nice little boards, and they measure 10.5mm x 12.57mm x 1.7mm thick.  I use these to make replacements for 2SA798 transistors, but you can use them for lots of other things as well.  I have shown a picture of a completed 2SA798 replacement, but that is not included--this listing is just for the two bare boards in pictures 1 and 2.

Assembling these is simple, but it's not that easy, and if you do not have experience working with SMD (surface-mount) parts this may not go well for you.  The new dual transistors are really tiny!  I use a very fine-point soldering iron, very thin solder, and a steady hand, though a hot-air station would work great as well. 

These boards are marked for a dual PNP transistor, so if you have a dual NPN then the "BCECB" markings will be incorrect, though you can still use them.

US shipping and handling is $6, and international is $20, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
