I just finished one completely on doughnut board. That was a royal pain. I'll take SMD stuff anyday, but wiring doughnot board is a pain. But the signal goes in a 1000uf cap, a 330uf cap, .1uf poly cap, other side of the reg, it goes in a 100uf cap, and 10uf tant. And I had to wire some resistors in series and some in parallel to get the values I needed for the 1k trimmer.
I did add a diode to the input. The 30v RS power supply was running at 35.2v and I wanted a lil under for my 35v caps. Also, the closest thing I had for a LED resistor was a 10k one and without an amp hooked up, that thing burns forever hehe.
All this for a clean, stable 24.6 volts, which feeds the charging/power circuit in my little amp which needs a whole 17mA, as soon as my batteries come in.
Sorry, no pics. Those screws in the RS plastic boxes are tough. No way was I taking them back out.
