Today I completed my Darling amp based on the schematic from Tom McNally's website. It took about 5 days to put this together. I used a smaller Hammond chassis, 10"x6"x2" and had enough room without component crowding.
The amp worked first time I plugged it in, I didn't let any smoke out! The Radio Shack speakers shown are not efficient at all and the amp sounds nice and loud enough for something that is only 3/4 of a watt. I will try it on my 96db Cerwin Vega's D5's tonight.
I tried to utilize the screws already used to hold the terminal strips but had to drill 2 holes on the side to bolt the choke in place.
Here is a photo of it.
