@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?

@gsuberland @lynn Look at the size of the transformer, yup. 60 Hz are BIG waves...

@gsuberland @lynn Looks like it's rawdogging the diode bridge: https://www.retrocmp.de/imsai/imsai_p05_psu.htm

@gsuberland you get unregulated +/-8V and +/-16 rails :) you’re supposed to do the regulation on each s100 card separately depending on your needs :D
