I have several Powerstat Variable transformers for sale. This would be Model #L21 made by the Superior Electric Company. It ranges from 0-140V and they are all in very good condition. I am located in Ontario, Canada so shipping would be a factor. I would like to get about $125 a piece for them. If you are interested, please let me know and we can put something together. PAYPAL is the only form of payment accepted.
