This page lists prices for customers in Australia, or who are overseas
but wish their machine to be delivered to someone in Australia, who
will return it to them.
To the TR-909 page:
../ for full descriptions of the following.
To the
../prices-int/ page for customers
who are outside Australia.
These prices include GST and are for payment with cash or transfer to
our bank
account (we will email the details).
After your machine arrives I will discuss the modifications you want
via email or phone. I will confirm the work to be done with the
total cost. I can give estimates of repair costs, but not
quotes. Very often, while fixing one thing, other faults become
apparent, and sometimes new faults develop which were not present at
first. TR-909s typically have one or more noisy transistors, but
it is generally impractical to replace all the 122 or so transistors of
this type in the whole machine.
The following lines can be copied into an email, deleting those which
do not apply. The items below
do not include freight costs. Please see
../../freight-insurance . TR-909s are too valuable to be sent by Australia Post.

if the above in-situ cleaning does not make
