corrosion

Shventus, that was great info on ACF50! I have an old amp lying around, I wonder if I could get it to work if I dipped it? ;-)

thanks guys. The issue is actually with the circuit board inside so its just not cosmetic on the outside. I found some pellets which slowly evaporate and create a vapor which inhibits corrosion which I am going to try. The aircon/dehumidifer route simply is not feasible in a house which is as open as mine is (hell I don't even have windows , just screens, on two sides! Plus thats the point of living here, not to be boxed up inside a hermetically sealed environment. So far, the tube preamp is the only thing really taking a beating and that may be because it is so open to allow heat disbursement from the tubes. All else seems find so far. Perhaps the pellets will save that (it is in for repair and the manufacturer said the circuit board was looking might corroded from the salt) - still works but I'd like to keep it going for a while. I think what will happen is if and when it dies, I'll have to switch to solid state which has a more closed design by its nature. I'll let you know how these pellets work!

Cheers -

Hoffman enclosures has corrosion inhibitors. But they're used in closed boxes, so the maintenance/replacement schedule might be quite high.
