Below: The amplifier schematic diagram. Note the plate choke on the 6SJ7 pre-amp. This

“Australian Made” is an
on-going series of
articles documenting
locally made ciné
equipment. If you have
something in your
collection – we would
love to hear from you.
It doesn’t have to be a
major piece of
equipment – many
accessory items
(winders, splicers, etc)
were made here.
