Hi Dave,

Thanks for answering the questions. I hope you can figure out the IC. I found 
an OB-1 a couple of years ago with a bad power transistor but couldn't get it 
to work. The number on it was 7808, it took me a while to realize that was 
the date code, not the part number -- DOH!

Your indication of a wirewound material is interesting since there are very 
large wirewound resistors. You've got me thinkin! Always a good thing.

Good luck!
John B.
