It is tough to test capacitors correctly, it requires multiple tests to troubleshoot for bad capacitors: Given all of that, the keys to troubleshooting tube equipment are to test the capacitance of each cap to verify that it is functioning and test the leakage to make sure it is not leaking current between circuits. The contractors did not reach any definitive conclusions but very quickly the prospects of a radio station in Haik Valley took on a demanding nature and immediate decisions began to be made about the construction as the plans for the Pacific Naval Air Bases took on an offensive position.
