Last night I opened my 512k to record all its capacitors (I think I've found a way around my worries about lead, so now I'll be ready to replace those capacitors!!! 
).
But anyway, once I had the case off I made the decision to just remove the analog board altogether, because otherwise I wouldn't be able to read the markings on those capacitors. Besides, the analog board was put in wrong and didn't seem to reach one of the little plastic clips that holds it on near the top of the machine.
My word! The anode cap was so incredibly tough to remove last night that my thumb is still sore today! I reviewed tomlee59's classicmac2 PDF and I realized I was doing it right--pinch hard with your thumb and index finger while pushing in towards your thumb and out towards your index finger. I guess the Mac Plus in tomlee's PDF was built differently, because my 512k's anode cap was a bit different. I ended up just lifting the rubber suction cup way up so that I could see how the little clips were held in, and finally after squeezing it at the correct angle I was able to remove the anode cap altogether.
Something else interesting I noticed: I'm not absolutely positive, but it seems to me that this analog board was defective at the time of its manufacture. In one spot on it is stamped the word "INSPECTION", in another spot is stamped "TEST 2", and there's a 5-digit code that looks like it was written by hand with a pencil. Not sure if it's common to all analog boards or not, but I just thought it was something worth pointing out.
Well anyway, there's my Mac adventure of the day...I'm hoping to get re-capping experimentation and re-capping itself done very soon, so I'll post back once I do all of that for more results!
