RE: Classic Mac Sound

Transformers are an interesting element of the audio chain-
The can generate noise
they - in the form of output x-formers- define the frequency response of the amp

however if well made- can make a unit be sublime-

putting that 'tar goopy' stuff in does a few things -
1: if done well, the material can get into the air spaces to keep the transformer quiet (from mechanical noise)
2: protect the windings from the lams - consider it added insulation
3: enable the transformer to be more uniform with respect to heat - and to then transfer the head to the external surfaces-

This is usually called 'potting' or potted transformers
not many people do it any more, as it adds expense...

but some of the best amps made have potted transformers-
Happy Listening
