I've got IBAM installed. Infrequently I test to verify the tubes are working (outputting) within 10% tolerances of each other. Today I discovered one of the adjusters adjusts upward fine but will not adjust below 35.5mA. Does this mean the adjustment pot has gone bad and needs to be replaced? (not an easy fix as soldering a new pot is going to be challenging for me) 35.5 is still within the 70%-80% range of max wattage. Thanks.
