Also listed on ebay, but you save $50 buying on USAM, because USAM is the best place to buy!

*** Fedex ground shipping in the continental US only ***

This crated transformer is over the 70 pound weight limit for residential delivery, but it can ship to a Fedex store, Fedex authorized shipping store, or to Walgreens, that has "Hold for pick-up" service for Fedex shipments.
All you need to do, is search for one of these stores near you, provide me that shipping address of that Fedex store, or Walgreens store, with your full name, and contact phone number, to add to the shipping label.
When the shipment arrives at the store, they will call you, to inform that it arrived.
Very good solution for being able to receive "over the 70 pound weight limit" shipments.

If you live outside of the US, you can do some research, to see if there is a shipping agency that's located in Northern part of New Jersey, USA, that I can bring the crated transformer to, for drop off. You will need to have an account set up with that shipping agency.

I recently did a sale, with a buyer from Poland, that found a Polish shipping agency near me, and the shipping worked out very well.

*** Local pick-up is also welcome ***

There are now 7 transformers available for sale. Price is for one unit.

Topaz line noise ultra-isolation transformer. The ultimate isolation transformer.
Retail price in 1998 was $2800 !!
Lightly used, in good working condition.

Model#: 91007-11
This is the largest transformer Topaz makes for single phase operation, with plenty of current to run the largest amplifiers, or high power equipment.

126dB line noise suppression. 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.

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.
Being that the secondary is also  dual 120 volts, you can use each 120 volt secondary winding to feed a monoblock amplifier.

For the best line voltage stability for output of the transformer, would be best to connect the primary of the transformer (with the two primaries connected in series) for 240V operation, and primary wire cable direct to your electrical panel, connected with a 2 pole circuit breaker, making it run in 240 volt operation.
Of course, electrical work performed by an experienced electrician!
This transformer is best suitable for people that own their own home, that can have these installed and wired properly in their home.

The transformer draws very little current, about 75 watts, when there is no load on the secondary, so the transformer can stay powered up all the time.

Each secondary winding is rated 30 amps @ 120 volts X2 (3750W each output).
Or, secondary windings in parallel, is rated 60 amps @ 120 volts (7500W output).

Do keep in mind, that this is a large piece of 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 135 pounds, plus the weight of the shipping crate with thick foams = 150 pounds.
Local pick-up is welcome, or can ship FedEx ground to a business, or Fedex store, or Walgreens, as Hold for pick-up.
If you have a freight account, you can also make freight pick-up arrangements to have the transformer picked up at my home in West Milford NJ 07480.

This large 7500VA 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.

Retail price, when new, was $2800 in the 1990's. 
These transformers are used, removed from a working environment, in good condition.

There are nor returns on this item. Sale is final.
You will receive a working transformer.

Any questions, feel free to ask.
