This is list of electronic equipment that I have restored to working
order. The equipment is special because it uses valves in its operation.
It is all obsolete and most of the manufacturers have gone out of business
or amalgamated under different names. However, their equipment still lives.
I have endeavoured to replace any faulty component with the correct vintage,
to keep them as original as possible, but sometimes the parts are difficult
