A Question About Transformer Outputs

[tumbleweed]

Hi Ted,

I was wondering if you could answer a question I have about transformers on outputs, specifically about what happens when half the secondary winding gets shorted out by using an unbalanced TS cable (in the case of TRS sockets). I’ve seen it mentioned that this will damage the transformer, but I’m having a hard time working out exactly why this should be the case. Thanks.

Sorry this has taken so long…. Have been tied up with new projects.
Regarding using TS connector on a transformer output, if the transformer is wired correctly with the secondary wired between tip and ring, then ATS connection is perfectly OK and just as good as a balanced TRS connection. The problem that you imply is if the transformer has a grounded centre-tap. In that case then the output would be shorted out with a TS connection. That situation is unlikely as nowadays the secondary winding would not have a ground connection.
