Parts List for EMEM2 and EMEM3 7/24/99 Tube: I have a few of the straight 18" EMEM2 tubes available. These can also be made by Robert Randazzo or Barry Allred. The high pressure phanotron for the EMEM3 can be purchased from Bill Cheb (780) 465-4960. Transformer: Marlin P. Jones (800-652-6733) has the 4 amp 12 volt (6-0-6) stock number 7840-TR. They also stock the 10 amp 12-0-12 stock number 7846-TR. The 10 amp model is much larger and heavier. Bridge rectifier: Radio Shack part number 276-1185 is one of many sources. Marlin P.
