Warming up an IMSAI P/S

Ok, so I have a 15W bulb in series with the P/S and it lit up. The fan
didn't start blowing until the second time I powered up, but its blowing,
albeit very slowly due to the limited power I assume.

I didn't go the full Tony route because doing so would've required
desoldering the entire transformer which wasn't an attractive prospect.

I measured the voltages across a power connector and got 9.4V, +17.56 and
-17.86. A little high but I attribute that to a lack of a load.

At this point I feel pretty comfortable that the P/S is working pretty
well, which surprised me. I expected a fight (but was hoping for the
results I got). These old machines just refuse to die.

I'm going to let it warm up for about an hour before I start plugging in
boards.

Thanks to Dave, Tony and Tim for your help!!
