Hi Sam, Not sure if this is private or not, apologies if not. I think it was you who refurbed my TSR-8 years ago. Are you willing to consult by email if I pay for your time? (Paypal/Venmo/mailed check, or whatever). It will probably be one or two emails. I can work on it myself, just need some guidance. Thanks for your consideration. --Nick Burnett, Mt. Desert Maine.
