What is the best approach to follow in restoring a radio?
A.) The best sequence is as follows: First, open up the radio and take photos of the inside and outside. These become a very handy reference. If a brittle wire breaks off, this step can save you a lot of time in searching the circuit diagram and the chassis to figure out where it was attached! Clean out any obvious dirt that you can reach. I usually like to use methyl hydrate (“wood alcohol”) and Q-Tips, to get rid of the dirt. Do the initial testing without the vibrator. Proceed to replace all the capacitors, one by one. As you are doing this, you will have better access to the underlying chassis as each capacitor is removed. This will allow you to clean out more dirt. As this proceeds, you should try and check every resistor that you come across by measuring it’s value and checking against the schematic value. If the reading is 20% or more higher than the listed value, it is defective. If it is lower, then there is something else in parallel that is preventing a good measurement. You
