Audio output transformer location
Is it better to mount the transformer on the printed wiring board or the speaker frame itself? I think the speaker is a better spot b/c it makes the board cheaper (less holes, less space) but will it adversely affect accoustics? I don't notice a difference.

So it is actually better to mount the transformer onto the PWB then. I have
come across it mounted to the speaker a lot on older radios though. They sound so well compared to modern sets in my opinion that I thought this may have been a better way to do it.
