We'll get this worked out after Christmas..don't know what the big
discusssion is about. Both IC's are available..if it calls for a 7837..use a
7837...if it calls for a 7838..use a 7838.
Unless this is going to be another 110/220 discussion.
This is not a modification, nor should it be relevant...since both IC's are
readily available.
