Your problem will probably be resistors. Those colorful ceramic resistors are notoriously unreliable and usually way out of tolerance; I always change them all- it's just not worth the hassle of continually repairing the radio(s).

The low value resistors are equally lousy; these look like wires with sleeving and have solder lugs crimped on the ends. These are very intermittent and I always change them too with modern resistors (half watt is fine in most cases). When you replace these you often need to add new ground lugs so that you don't have ridiculous lead lengths. Don't worry about placement either; these AK's are not VHF or UHF. Just put your new components wherever they fit nicely and with neat shortened leads.
