The thread about de-potting NST's sparked a question about potting compounds--- Does anyone know a relatively cheap source of paraffin, besides candles? I'm planning to eventually pot my power supply in something that is non-toxic, and won't leak. I have heard about mineral oil + poly combinations, and I may go this route if I haven't yet found candles, or some other source of paraffin which isn't prohibitively expensive. --Mike
