Thanks to all who commented on the magnetic puck.
I wasn't too concerned with it since my unit is soon to be swapped out. But last night under close examination I too had a teeny rough spot which upon removal corrected this issue.
For those considering an LPS for this transport, I placed an order for the Fidelizer Nikola II on July 6th. At that time parts for the actual 20v transformer were on back order. A follow up 2 days ago brought information that the core materials have arrived. The unit should be completed about Aug. 15th.
It's unclear to me if the raw materials are available to build multiple units at this time. If interested contact Keetakawee. So far he has been fantastic to work with.
