If your bombarding temperature gauge (or other meters for that matter) looks like this the answer is YES! Trying to keep old equipment limping along when it is past its time is usually a false economy that leads to more expensive things – like having to remake countless units that went bad due to false readings from an old worn out gauge. Keeping equipment in good working order and repairing it when necessary goes without saying. But there comes a time when you just have to let it go. Do yourself and your customers a big favor and be realistic about it. This one should have been retired decades ago.
