Chad,
Have not tried to repair the fried relay, as I was able to buy a lot of 3 (lucky) some years back. Also, your particular model may already have the series resistor or other mod added later. You will have to look at the board ( ummm... A10..?) to see what is actually there. And, you might as well invest in the CLIP from Artek if you want to do component level work. I have discovered that the .pdf scans you get from Agilent on the old gear are pretty bad, and no text search capability...
