I recently found a pig for sale. I emailed the guy about a certain abbreviation that was in the ad (N.T.). The guy emailed me back and said he thinks that the N.T. means no taps. So here's where the questions come in. If this transformer doesn't have taps, how much do new taps cost and where do you get them? If they cost alot then I will probably forget buying it there. Stupid question, but what are the taps actually for? What do they do? -Chris
