Audio Output Transformer If I ask Radio Shack for specs on it, they'll tell me the size, and the color of wires coming out of it, that's about it. I just need to know what it's called in the real world, as I want to order one from a parts house like digi-key, that is made to mount on a pcb. It's a line matching transformer that attenuates a ...

After searching the usual sites it seems the cheapest is actually from Radio Shack: http://www.radioshack.com/product/index.jsp?productId=2102703 It's only $10.49 USD. Supposedly it can put out 2A, it has an all metal enclosure and it comes with clips and wire leads. A similar part on digikey or mouser is over twice the price.

It's just a plain old audio output transformer. You already have the most important specs: 900 ohms primary impedance with a center tap, 8 ohms secondary impedance. Since this is a learning kit, I'm assuming that it is low power, maybe a few hundred milliwatts. I suggest one such as this from www.mouser.com as a close replacement: Catalog # 42TU008

Conversely, a transformer with a turns ratio of 1:2 would be called a step- up transformer since its secondary voltage would be twice that of the primary. Since a transformer does not create power, the power output from the secondary of an ideal transformer can only equal (and in a real transformer only be less than) the power input to the primary.

Audio Output Transformers are most often use in vacuum tube amplifiers to match high impedance (tubes) to 8 or 16 ohm speakers.The Transformers primaries range from 600 to more than 10,000 Ohms. Very well designed OPTs such as Lundahl or James have very good frequency response over the audible spectrum or 20Hz to 20kHz.

In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

Guys I bought a transformer from radio shack - (273-1512) Im not the electronics guru and need help. How is the input / output determined ? There are 3 wires on one side, 2 on the other..... a standard setup but I know nothing about what is what.
