Vintage Synth Repair

Hi all,

I'm trying to fix my OB Matrix6R, on which the left channel doesn't 
play. The last stage is a NEC C4082C dual opamp (datasheet attached to 
Files section).

I wonder whether it is possible to replace it with a 4558 or a TL072 
opamp, safely ?

There is also one 4053 that I suspect. In case I need to replace it, 
what could be a good substitue for it in case it can't be found ?

Thanks for any advice.
