I have more restored relay boards. Both early type with the post insert and later type without the insert.
I am requesting you old core board to be able to continue this service.
We tried a spray on sealant on two boards which has a lumpy appearance.
They are 100% as functional as the smooth ones. Offering $25 off on them.

One has the threaded insert for the relay cover post. The other two do not have the insert and use the late reboard cover without the hole.
Boards were stripped of the old tar on the bottom, cleaned, tested and resealed.
$150 shipped in the U.S. without a core.
$125 with a core.
