Today I got one of the twist-lock cans replaced, 200 uF + 50 uF + 50 uF + 50 uF. Quite a fiddly corner of the chassis, and fun teasing the component leads from the capacitor's lugs. Even more tricky to get the tip of my bigger iron onto the two twist lugs that had been soldered to the chassis.

With that done, I documented the next difficult multi section 40 uF + 40 uF + 40 uF + 20 uF, and set about desoldering and detaching the connections.

On the 200/50/50/50 I tested with the capacitance meter. The 200 section read 300 uF, two of the 50's read about 68 uF and one only a few hundred nF. The other test I did was to charge the sections up with a 9V battery and look at the discharge rate (10 Megohm meter). Most looked very poor, especially the 200 uF which would discharge to zero in a couple of seconds. The 2x 1000 uF can was also tested, each section reading around 1300 uF. These seemed to hold better, and may even have been useable, but the Hayseed Kit included a nice replacement.

Funny, I thought the work would go faster, and I would have the cans all done by now, but after playing a full game of soccer (football) this morning, I soon found myself tired standing at the electronics bench.
