I'd echo that - no problems with amplifiers stored in a seaside caravan
for many years. One option to consider is getting the aluminium parts
chromate passivated (Aludyne or Irridite in the US?). Costs vary wildly
but you might find a plating shop that will do a batch for cash. Make
sure there's no confusion with anodizing - which you don't want.
