@med6753 Here is the parts location, close to U660 on the vertical board.
Edit: To be fair to Tggzzz he did mention these parts to you but referenced page 17 so I'm wondering if you both have the full full manual or not? The one I just downloaded has 192 pages and is the Rev B, March 1976. and if you want me to email it across to you, give me your email address and its yours my friend.
