Attached is a copy of the board I need to build.
Is anyone able to tell me what I will need for this, and would be able to give me a brief guide on how to build it?
If I need any further assistance I'll let you know. I thought I had to build said model of the chip, but I have a small 555 chip in an object that needs repair, and just needed to clarify that the schematic wasn't a totally different chip. Now I've researched the chip and can make the necessary repairs.
Q19. You could probably use two transistors with the emitters and bases in parallel, separate collectors. But so much of this circuit depends on the matching of parts and the fact that they are on the same substrate make it *almost* impossible to reproduce it using the same circuit. Functionally, no problem, but not identical circuitry.
