Hello Mr. Adams.
If someone can provide me with a complete serial number for the NT-505 in question, we can look into this immediately and determine where the holdup lies with regards to furnishing parts. Our parts supply here in the U.S. is replenished by the factory overseas. Given the NT-505 is a current model in production, there should be no issue with the existence of parts. Could a part be out of stock here locally? Yes. Many things are impacted by Covid-19 and the steadiness of supply chains is certainly no exception.
As an owner of an NT-505 and CG-10M yourself, I can put your mind at ease by telling you that whatever you are alluding to that is being touted in the forums is not even remotely close to accurate.
