I've powered up the SOL-20 and nothing smoked

First, I pulled the 17,000uf and 54,000uf electrolytic cans, and
worked them up to 15V through a 10K resistor. I later stepped this down
to 1K. I let each cap "cook" for about 48 hours. I did this while I
was waiting for an ESR meter I ordered to come in. <URL:

today, and I checked the two big caps and the two 2500uf caps on the
power supply board. They were right in spec.
I then reinstalled the caps and disconnected the supply from the
motherboard and the riser card, then powered it up through a variac.
The supplies looked good, so I plugged them into the motherboard and
riser, attached a monitor (which I first had to get working...) and it
sorta came up.
Well, I ran into a very unexpected glitch. ACE Hardware sold me a
not-just-used-but-smoked outlet. In a new, sealed box. I'm not quite
impatient enough to pull one out of the wall, so I'll be up on jacks
till tomorrow evening.
Bummer about the keyboard. I hope it's an easy fix. To tell the
truth, keyboard problems are one big reason I lean toward systems that
can run with a serial console.
