fp-33 inside

One of the first things I did was take it apart which is very easy as it only involves sliding off the U shaped cover.

The big transformers are the output transformers.
I was looking for the power supply as it was very noisy.

I found it well shielded under the battery holder, the board can be removed without sliding off the cover.
I found no other way to stop the screaming noise then to remove the nylon srew that holds the transformer.
It is still noisy but at least it is bearable.
