Hi, I have been gifted a cr-1040. The 1040 has been in storage for almost 20 years and in our family since new. It has never had the cover off and doesn't have a mark on it. My goal is to power it on using a variac with the hope of just gently bringing it back up. My problem is, I don't know whether to take my time and use small 10v increments spread out over hours, or just get right to it. I have searched and there doesn't seem to be any real consensus. My hope is that someone who has first hand experience will be able to offer some suggestions. I attached a couple of photos. The 1040 is in its fresh out of storage condition with very little dust.
