## Description

LINE MATCHING TRANSFORMER

Review: Works great. Very inexpensive solution and quite fun for experimenters ... - These are handy for matching various impedance at audio frequencies. I used mine to step down the headphone impedance of a vintage Heathkit HW-8 radio from 1000 ohms to 16 (to match my Sennheiser headphones). Works great. Very inexpensive solution and quite fun for experimenters who want to just learn about audio impedance.
Review: Just like originalvT725 - Good for antique radio repairs

## Questions & Answers

**Q: What's the winding ratio?**
A: Hi Robby, this site should answer most of your questions: http://makearadio.com/misc-stuff/t-725.php

**Q: connected to 120V mains what are the output voltages?**
A: As someone else answered this transformer is designed for audio matching and does a terrific job at that. Yes, some audio voltages are high with tubes like 90v but the wire gauge will not support much current like a 120vac input power transformer. So I don't think any one can tell you the voltages as it is not designed for that function. But if you persist and search the 'net you can find a site where someone has listed the resistance/impedance of all the windings.

**Q: Which wire is the common or the positive for the 8 ohm speaker connection?**
A: The transformer T725 received in my order had 2 black wires for the 8 ohm speaker outputs.

**Q: Will these work with a 70 volt or 100 volt system?**
A: It will work with 70 volt rms , 100 volt peak systems.  4 watts power per speaker.  Has taps for 25 volt systems also.

### ⭐⭐⭐⭐ No instructions, but you can get by
*by T***E on May 5, 2012*

This matching transformer is a good buy. It does not come with schematics or instructions, but you can get these online. If you are using these to power crystal radio speakers, be sure you get low-wattage speakers with fairly rigid cones or you may not get the audio output you want.
