Does anyone know where i can get a manual / service manual , for a AMBER model 3500 distortion . noise measuring set .  Searched and searched with no luck , can not find any info on web about this units ?.

Any info would be greatly appreciated .

Are you sure it's a 3500? I think that was the very first Amber analyzer model, and I'm rather surprised that one made it to the UK. I do have three Amber 3501 analyzers, and I believe that the circuitry may be similar. Mind, these days I have trouble remembering to put on pants before leaving the house, so who knows...

yes 3500 , i have 2 , one in fair condition and one in good condition , both have dead battery , one does take power the other does not, so are they worth the hassle and time to try a repair ?, Thinking i may get one good one from the 2 ? , but like i say can not find any info on the web about them.
