Is the new transformer the exact same model or just the same make as
the old one?
If not, then it may be the wrong specification or as you say the
buzzing may be from the light switch - does the switch have a light
dimmer? as they usually only work with electronic transformers and
maybe your new one isn't?

Hi ,

Same make, same specs - model number of the original no longer in use.

Buzzing definitely from the light switch, which does have a dimmer.

Both the original and replacement transformers are suitable for use
with dimmer switches.

Sorry if that makes it even more confusing!
