I've recieved various components, home theater system (2008) & albums from late 60's-70s. Problem being is the former owner had a problem w/German cockroaches. I'm not interested in any potential lingering eggs. I do not care for posion or heating 140* F for a couple of hrs. Me choosen option is a couple of days of deep freeze. Six * below 0 F to be exact. The KA-7002 is to be the next in line. Are there any issues I should be concerned about storing at this temperature for a few days? As well any similar general advice on albums or speakers/subwoofer would be appreciated and thanks in advance.
