WELCOME @Rick K!
I second what Charlie said about Nelion...great service and excellent work.
Also, you might want to read up on the MKII upgrade for your M-1.0t amps.
WELCOME back @jerry6!
That M500t MKII is a great amp.
May I suggest you investigate a Carver C-1 (w/ BillD mod) preamp to go with it.
They make an awesome combination.
