@lynn holy shit how much current is that thing supplying? I can't imagine needing that much smoothing even on a linear supply. or are they not even doing active regulation and it's straight up rawdogging off the diode bridge?

@lynn 🎶 And when they turn the power on, it's sure to dim the lamps With plus or minus sixteen volts and fourteen hundred amps – Frank Hayes, "S-100 Bus"

@lynn Color me unimpressed with IMSAI's use of 15VDC rated capacitors (assuming those are factory spec) on a supply rail they rate for nominal 13.5VDC. I never before noticed that IMSAI did that. Aluminum electrolytics don't need DC bias derating like ceramics, but they should still be specified with some headroom. 15V is only 11% over nominal, and line voltage can easily be vary over time by more than ±11%. :-(

@lynn As a schoolboy I worked with a cast-off LACE MK II analogue computer. Which was valve based, and had big power supplies with very large capacitors. My little brother discovered that if you took a spare one of these, and clamped its terminals in a stand nicked from the chemistry lab, and then put 6.3v AC at many, many amps across the terminals from one of the computer's massive valve heater transformers, the capacitor can would shoot right across the school playground.
