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.
