SP-600 from hell:need knobs, handles
"Brian Hill" wrote in message news  "Richard Knoppow" wrote in message I will pass along a method of cleaning used at Hewlett-Packard many years ago. We washed equipment sent in for overhaul using a paint spray gun filled with warm water and dishwashing detergent. This, along with a soft brush, would remove most dirt and junk. Once washed the equipment was rinsed off using a sprayer hose attachment and dried in an electric oven for several days at about 130F. Remove anything that can be damaged by moisture, meters for instance. We also found a high rate of failure of hermetically sealed transformers and chokes. This is counterintuitive but if the seal is leaky moisture can get in and has a hard time getting out again despite the baking. I don't know what effect this will have on the ferrite cores in the SP-600, maybe none. -- --- Richard Knoppow Los Angeles, CA, USA You dont spray inside the cans. You gotta use your head. I otta make a video. BH Well, you can seal off the holes the adjusters come out of. I would take the cans off because they will trap moisture. -- --- Richard Knoppow Los Angeles, CA, USA |
