    I have one NEW AND UNUSED Topaz 91091-31 transformers for sale. These are great for use with DAC, headphone amps and pre-amps to clean up the noise coming from your mains. These can be configured to input or output 120v/240v and can also be wired for balanced power. I am asking $111 shipped including PayPal and insurance.

    Look here for more information on the benefits of these transformers:

    Here’s an example of how one would look with wire attached for plugging straight into a DAC or headphone amp.

    do they have a buzzing noise if you put your ear close to them/.

    If there is nothing between the transformer and my ears I can begin to faintly hear them at 2 ft. If obstruct that direct “line of sight” with something as simple as cardboard it drops down to about 10 in.

    Chances are youll have yours out of direct line of sight and/or will be further than 2ft away so I don’t think it will be and issue.

    No I just had 3 of them so looking to offload some excess. I currently have two 2.4 kva units, a 5 kva unit, a 500 va unit and two 125 va units.

    I have one new unit and one that’s in new condition buts has been wired. Here are the two 125 units and the 5 kva unit for comparison:
