Vintage Transformer, 10 volts @ 6 amps, Tested, Excellent

Description

This is a Vintage Transformer that has just been sitting in my basement for over 30 years.  It is coated in some type of firm black material so  that it is encapsulated.  The terminals are marked, 1, 2, 3, and 4.  1 & 2 are the primary, and it works fine with 120v AC input.  The Measured output voltage is 10 volts.  The transformer weighs a bit over 3 pounds - almost exactly the same as a 6.3v filament transformer that is rated for 10 amps.  Based upon that comparison, I think it would be justified to expect that a reasonable current rating would be about 6 amps.
I have numerous other transformers, and other items for sale, and if you purchase more than one item I will gladly combine shipping.  Depending upon distance, the USPS Priority Mail Medium Box might be the lease expensive shipping option.  Another option is Priority Mail based on weight and distance - which is less expensive if you are closer to Virginia.
