I have 2 service records and quite a few things were swapped out like 5 years ago. I need to pop the top and look for any bulging caps etc with my limited knowledge. Pretty cool have original manuals and marketing material they showcased at dealers also.
Looks like a split opinion on leave it on all the time or turn off. Need to think on it. Right now been on for 4 days and is dead quiet at the speakers unless an inch away from the tweets.
I have to say I'm enjoying it more than my MF A1008 which I consider pretty good.
