It's good to see their still working after so many years. The oldest one I know of at the moment is 28 years old and still going strong. Thats a little 6 i think.
Sorry got it wrong , I have the Max, 2 5A, 5b and ths old one which must be older than 26 years as the old guy died about 12 year ago and had been retired a while.
