Good morning and yes I can do anything to any Quad machines ever made before the 1990's...been doing it for a wee while now...tee hee...
Negotiating like this might take a very long time as I have literally dozens of machines - some fine, some rubbish, some in process of refurbishment and some not touched yet - I have made old Quad machines my speciality over the past few years - I will do a listing on here later today to show you what I am meaning with having many, so maybe best for you to see for yourself.
