Topaz 5kVA line noise ultra-isolation transformer model 91005-31. The ultimate isolation transformer. Far superior to any power conditioner or 'audiophile' isolation transformers like Equi=Tech or Torus Power. 146dB line common mode noise suppression (for reference, Torus Power has only only 80dB CMNR). Is about as good as power being regenerated for pure clean AC power. Also will reduce a 6000 volt AC line spike to 6 milli-volts! A great protection, if you have had lightning strike problems in your area. A forum discussion on the Topaz transformers: Lightly used, in excellent working condition. This is the largest transformer Topaz makes for single phase operation, with plenty of current to power large high end amplifiers, or high power equipment. The primary and secondary are wound completely separate windings from each other, spaced apart, and individually shielded, so there's no noise coupling between the primary and secondary. The primary to secondary capacitance is only 0.005 Pico-farads !! No standard isolation transformer has this good of noise isolation, such as the Topaz transformers. The primary and secondary windings are dual 120 volts, so they can be wired for either 120v or 240 volts (input and output). This type of high power transformer should have the electrical work performed by an experienced electrician! Do keep in mind, that this transformer has large iron, and large transformers do have a little hum, when they are on, so placement outside your living/listening environment would be recommended. Normally, the transformer would be located near your electrical panel, and the power output from the transformer wired to the location of your equipment, or audio amplifiers. The transformer itself weighs 50kg, plus the weight of the shipping pallet = 70kg. This large 5000VA Topaz transformer does not come up for sale often, and is far superior to any hi-end line conditioner, because of the completely separated primary and secondary windings. This transformer is used, removed from a working environment, in perfect working condition. If shipping is required, it will be placed on a pallet and shipped via insured freight for safe arrival. All enquires welcome and will be answered in full. Palletized shipping within the EU ~ 100 EUR by DB Schenker with full insurance. No VAT or duties for EU countries. 800 EUR + shipping (I have paid $499 for the transformer, over $400 for shipping to the EU and close to $200 in import taxes, so over $1100 / 900 EUR in total; selling only 'cos I just bought the 7.5kVA model).
