I just received a response from Elecraft. They are sending me a new bottom cover and a noise kit for some transformer noise that I had not previously mentioned here. While this will involve me tearing down the amplifier and then rebuilding it the outcome will be a properly constructed amplifier.
In all fairness they did offer to repair it at Elecraft but I declined because of shipping and insurance cost and not having appropriate packing since it was a kit. It was a good response I think. Thank you Elecraft.
