Thanks Peter;
Noted, Looks like this set is now going to end up in my shop. Customer just
called me, and was surprised I knew about it.
Any other things that you guys have run into on this set, let me know. Hate
to have to go the CRT/Yoke route. And even worse...find out after it wasn't
needed..;-)
