While living in England I purchased a Saunders/LPL 4500 enlarger which has a power supply for 240v. When I moved back to the States, I bought a 120v power supply through that well-known online auction. However, the outlet connector from the lamp house to the English power supply is a two-pronged male plug (enclosed in a housing shaped something like an arrow). The female receptacle on the USA power supply, however, is a four-pin receptacle. Any suggestions for a (reasonable) solution?

Photos of the two power supplies and their receptacles are attached. The USA unit is on the left, the English unit on the right.

Cheers, Dave
