[Elecraft] Wrong PIM nuts in KPA500 kit

[Michael Blake]

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.

When I had temporarily installed the left hand side panel in the middle of construction I failed to notice this and just installed screws that fit (one 6-32 and two 4-40) but during final assembly it became obvious that the 6-32 screws would not fit in 4 of the 6 positions.
