This item being offered is a new power supply for the Bulova watch cleaning machine.  I had 10 of these made in the mid to late 1990's when the originals weren't available.  I just found 3 of them that were left over from previous rebuilds.  It included the schematics for installation.  I believe the Bulova branded machine is the same as the Mark II Watchmaster machine.  Basic knowledge of electronics needed for installation.  Selling in AS-IS condition as pictured and described above.  Buyer to pay $15.00 shipping US, check on out of country.
