To All:

I am looking for a transformer-coupled transistor audio amplifier design. Can someone share with me websites, articles and schematic diagram if you have. Thank you!

 

The name 'Bailey' comes to mind.

The book by Linsley-Hood gives a wealth of detail

In 1955 Philips made a transistor radio with an output transformer.

 

Minor (or major) mistake.

Well spotted. Should I now sell my shares in Philips?

 

Here as a transistor amplifier from 1960. It has the usual germanium transistors and a driver transformer.
The output transformer is unusual because the speaker is connected to it like an auto-transformer and a separate winding is used for negative feedback.
