MAC 1900 receiver question

Hi all. I just came into possession of a MAC 1900 receiver. It sounds pretty good out of the box. I am not sure that it has been turned on in a decade. The right side is not as loud as the left though. Is there anything special that I should be looking for on this or should I first just deoxit it? Thanks in advance.

They always need a deox of the switches and a faderlube treatment of the potentiometers.

I always check for tone control alignment......easy to get a 3 or 4 dB volume discrepancy, which even sounds worse than that if it happens in the more critical frequencies.
