I did that...  without the 4mb simm, it still gets hot.  A human thermometer went all the way up to 108 degrees f.  I had to stop it there to keep the thermometer from breaking.  So it's at least 108deg f.  Weird.  I didn't remember it getting that warm.  Just slightly warm but not like this. Everything else feels cool.

It's been about 10 days since I've last washed it.  I used a bicycle pump with the special valve to shoot air at something (different from the one you use to fill up a ball).  No compressor yet!

Can one of you check the voltages for me on the c2, c4, c5, c7 caps?  I'm getting :

c2: 0v

c4: 3.94v

c5: 3.94v

c7: 3.94v

I think those voltages are low.  If so the problem might be in the audio section somewhere.  I'll keep hunting around in the schematic to see if I can narrow it down further.

It's definately the motherboard.  I've removed the hdd, hdd power, floppy drive, keyboard, monitor, speaker and fan cable... same issue.

do me a favor and pop out that ram simm and see if the cpu still gets hot.

also you need to get a legitimate temperature from an IR temp gun or even a thermometer touched to the top. 

normally the LC-III cpu does not get that warm even when running @33 mhz Re-clocked.

120F probably at the most.

- sometimes in the washing process water can still pool under i/c's did you dry the board with a compressor before you tried it?

your cap job looks to be ok though.
