This is the first time I've used an audio transformer so I'm really not sure what I should be expecting to see and the data on the LT700 seems pretty thin. So the question stands - on the config in the OP, from a 1V PP input, I'm seeing approx. 15VPP (between approx. 1V and 16V) at the output of the collector and approx. 800mV at the 'positive ...

Wiring the Speaker to the LT700 Transformer

LT700 Transformer Mounting and Wiring. Mounting the LT700 transformer is very simple in this build. The one I got was from eBay, and it was a PCB mount type with short leads. However, I discovered that if you bend the leads by approximately 45-degree angle then it is more than enough to be used with the screw cup system.

The transformer is the wrong way round. The winding with the highest inductance should be the primary. There is something wrong with the inductances OR with the ratio 8V to 3V indicates the inductance ratio should be about 6:1 (8/3^2) With 0.55H on one side and 2.25m on the other, I read a ratio of about15:1 You should upload your .asc file to the Temp directory, so the …

Settings for simulating an LT700 audio transformer output in LT? ... To confirm - my priorities right now are to get the transformer wired up in the sim correctly with a 4R speaker/load on the outputs and to get the settings right for each of the inductors to be bale to reproduce what I'm seeing on the breadboard - approx. 8V PP at the ...
