Before I "discovered" Ghurd' electronic voltage shunt I spent a couple of hours figuring out the parts list for the old controller, so I might as well list it here. The grand total is $50.20 plus about $6 shipping for everything. That will make two units, so roughly it is twice the cost. It includes everything except the PC board etchant. This also contains ONE "muffin fan" which really is not part of the controller but an additional load it uses and over $8 of the total. It is used. So for anyone who wants to play with vintage stuff, have fun- here it is (well really, Go Ghurd):
