I have this old vintage amp, a Technics SU-V9 that when powered for about half an hour and well warmed up emits this awfull plasticy smell. Are the residues this emits of any concern for health ? This seems to be a strongly well build unit but I think the pastics are starting to desintegrate a bit, maybe they weren't of the same quality of today's stuff (the plastic part not the rest which is probably the opposite I know...
).
Any thought on this ?
And what about those even older 70's amps, are those even worse ? Note that although the V9 doesn't have plastic on the outside casing it does have on inside cables, which the 70's amps do too I bet...
THanks!

If you were more specific in your description than "weird plasticy smell" perhaps we could be more helpful. However, many consumer electronic designs still are constructed on cheap Urea-formaldehyde substrate (often grouped as phenolic) PCBs, These smell of their constituents, formaldhyde and urea which, if you were paying attention in high school, are low level irritants at the concentration released from warm PCBs.
Some would describe that odour as something cats excrete but perhaps you have something different like leaking electrolyte from well outdated capacitors or otherwise failed components. Check for the area of strongest odour and heating of parts there.
