The use of 6A5's makes your set a code 125 or 126. Service bulletin
258 shows a 2 Meg resistor was added to prevent clicks when tuning the bass compensator 'tone' control on a very strong carrier. Code 125 is manual tuning and code 126 is auto tuning. Pot 128 is removed and the cathodes of the 6A5's are grounded. John
