   | THESE ARE THE BIG DOGS! High Tension Generators. 240 VAC in at up to 260 Amps. 150,000 VAC out at 500 ma. These are Litton PROFEXRAY generators and they have been custom modified for use as Very High Voltage power supplies. The diodes have been removed and the output rewired internally for AC output. With proper ballast, they may be run on residential electrical service. Awesome arc will self start at distances over a foot across. Average weight 450-500 lbs. | $399.95 | Carl |
  | York 500:1 Step-up power supply with DC output. The transformer weighs almost 140 lbs. and contains dual center tapped secondaries. Input is 240 VAC at up to 150 Amps. Output is 125,000 Volts DC at up to 300 ma. The seconday output is connected to a full-wave non-bridge 125 kV rectifier in the form of 4 diode strips (see photos) which are connected in pairs - 2 forward biased and 2 reverse biased - with bare solid conductors (one is visible in the lower center of upper photo). This arrangement produces +62.5 kV on one side and -62.5 kV on the other side. This unit may be converted to AC output by removal of the diodes and cross phasing of the seconday outputs. It may be used in open air up to about 20,000 Volts but must be submerged in dry transformer oil for the full output voltage. With standared inductive ballast or solid state current control, this power supply may be used on residential electric service. | $149.95 | Carl |
 | TOSHIBA 25kV High Voltage Power Supply A Toshiba High Tension Generator manufactured to power medical radiographic equipment. This unit produces + 25,000 Volts DC (1 uA) with an input of 100 Volts AC at an insulated terminal on the face plate to which the instrument it powered was attached. There is also a BNC connector that has an output of negative 550 Volts DC. This compact unit measures about 5.5" W x 3.5" H x 8.5" D and weighs less than 5 pounds. With a proper insulated connection using HV rated line (e.g. 40 kV Television Flyback wire) made to the output terminal, this unit could have a wide range of uses in high voltage research and hobby applications, including powering lifting devices based on the so-called Biefeld-Brown effect. | $59.95 | Carl |

This is the power conditioner transformer from an IBM mainframe computer and weighs about 3.7 lbs. This versitile unit may be used at 120 or 240 Volt input with the secondary outputs noted in the lower picture and handles up to 20 Amps continuous. The high voltage tertiary winding is connected to a power factor balancing capacitor. A very useful power supply for many electrical projects. | $29.95 | Carl |

This is the main base (A1) power transformer from an IBM 5360 mainframe computer. This is the VERY big brother of the tansformer above and weighs 41 lbs. The 240 VAC primary can handle over 50 Amps continuously and the extremely heavy duty 8 Volt secondary is wound of 3" copper stip and rated at 100 Amps continuous. It can handle 4 times that momentarily. There are many other secondary windings producing other voltages at lower power. The high voltage tertiary winding is connected to a power factor balancing capacitor. This makes an awesome spot welder with no modifications. Shorting the 8 Volt secondary leads directly together produces a localized current of about 400 Amps without pulling enough on the primary to blow a 30 Amp 240 Volt breaker! | $49.95 | Carl |

Want to build your own welder or ballast inductor? This is same model as the above transformer with the secondary and shunts removed. About 28 lbs. | $59.95 | Carl |  |
This is the second (A2) of the 3 power transformers from an IBM 5360 mainframe computer. This one weighs 37 lbs with the cap. The 240 VAC primary can handle over 50 Amps continuously. The high voltage tertiary winding is connected to a 660 VAC power factor balancing capacitor. | $34.95 | Carl |

Giant Raytheon AC-1030531 autotransformer is an electrical hobbyist’s dream. This brute about 10” x 10” x 5” and weighs about 140lbs. It has 5 separate windings that can be combined in many configurations as a standard transformer or autotransformer or ballast reactor or even a combination. It is rated for either 240 or 480 VAC input and will give 25-50% over output in autotransformer configuration. The windings are #10 AWG magnet wire with a total of 35 output taps over the 5 windings. The associated schematic shows only one of many possible configurations. In this one, you have a 21 tap autotransformer wired for 20% overvoltage and two tappable secondaries. The possibilities for use as inductive ballast are almost endless from about 1 millihenry to 140 millihenries giving from less than 1 Ohm to over 50 Ohms of reactance on a 240 Volt 60 Hz. line and limiting current over a range from 4 Amps to the way over the 200 Amp limit of residential electrical service. See the manufacturer's scematic here. | $89.95 | Carl |

Toshiba isolation/line compensation transformer. This 240 lb. extremely heavy duty unit is designed to accept input from service lines of 208, 220, 240, or 277 VAC and output 240 VAC. It makes an incredible inductive ballasting device capable of holding hundreds of Amps in its magnetic field and that by itself will limit a 240 VAC line feeding the pole pig in the picture to either 20, 30, or 80 Amps WITHOUT EVER GETTING WARM! | SOLD! | Carl |

This is one of 3 primary coils from a 700 lb. transformer. It has 3 windings and with the core iron weights a little over 80 lbs. This makes a useful ballast inductor in the range for HV work by using various combinations of the 3 windings in series with the input line. The 2 most useful configurations give 8.2 and 19.5 millihenries inductance, which corresponds to limiting a 240 Volt line to 55 Amps and 77 Amps respectively. Take half of these values for a 120 Volt line. | $39.95 | Carl |
 |
100 lb. potential transformer designed to accept 7200 Volt input and to output 120 VAC. | $99.95 | Carl |
These transformers are step up transformers with ratios from about 16:1 to about 20:1. They range in size from a little over 9 lbs. to in excess of 15 lbs. each. One side of the secondary is attached to the frame of the transformer. The primary input is 120 VAC at between 10 and 15 amps and the output is 1900 to 2200 VAC at up to an Amp or so. We have multiples of individual styles, allowing the use of matched pairs/quartets for the various series/parallel designs for HV power supplies. | |||
