Vintage Synth Repair

thank you for the two responses. i assume i can clean the contacts myself? regarding the last 
service of this board, it's been a while. the problem here is that i can't seem to find a good 
vintage synth repair guy. i live in toronto and one would think that there would be a handful 
but i can't seem to find any good ones. anybody know any quality vintage synth repair people 
in toronto? any help would be greatly appreciated.
