This particular set seems to have had several owners and I've been told it originally started it's life at Radio Australia. The person I got it from had kept it wrapped in plastic whilst in storage and had not turned it on since 1997. 

I'm not sure about the origins of this radio. There is a label inside the radio that states it was calibrated for Radio Australia back in 1986. However there is also a identification plate attached to the front of the set.

 This would indicate that it was used in a military capacity for at least some part of it's life. The date code indicates that it was made some time in February 1962.

Along the way it has suffered it's share of distress and modifications that required a little work to resolve.

Power-up.

Power-up was uneventful with all tubes lighting and supplies settling to the prescribed values. About 25 seconds after power-up noise rushed from the speaker. After 8 years of silence the RA17 lives again. Note that with the exception of the mains cable and fuse holder and phone socket replacement there was no other electrical or alignment work involved in the restoration of this set.

Receiver Alignment.

The following note in the service manual makes it quite clear that alignment is generally not required.

WARNING! The receiver will, under normal conditions, remain in alignment
over an extremely long period time, consequently ALL POSSIBILITY
OF OTHER CAUSES OF LOW SENSITIVITY SHOULD BE ELIMINATED
BEFORE RE-ALIGNMENT IS CONSIDERED, and should then
only be undertaken by order of the Engineer responsible for the maintenance
of the equipment.

Elsewhere in the manual I found this,

With the exception of V5, replacement of valves will not affect receiver alignment.


Clearly, these sets are built to last and remain reliable well after they are taken out of service.

If you must fiddle or tweak do it with the utmost of care and make sure you are doing it for the right reason.
