Drive an audio transformer from an AOP. Good or bad idea?

[mudevilo]

Hello everyone.
I read on an electronics website that it was not recommended to use an AOP to drive an audio transformer.
Transformer which will be used to balance the signal output from a microphone for example whose amplification will be managed by AOP.
The electronics engineer on this website says that it is necessary to insert a transistor-based assembly between the AOP and the transformer, because transistors have a higher current capacity than AOPs.
What do you think?
Thank you for your feedback.

OPA ...
operational amplifiers ...

AOP stands for ampli opérationnel, in french ... Since GDIY is an english speaking forum you'll have more luck with "opamp"
the NE5534 is a great candidate

As with everything, it depends on the application. Some op amps are perfectly happy driving some transformers, some less so.
