Hi All, I got my TR-6 this week and noted that it has a hum in the audio even with the volume control completely down. I am going to look at the filter capacitors in the AC-4 today, but thought I saw an tip somewhere that there was another place to check, that can cause AC type hum in the speaker.
Question 2: I note the two wire AC line cable on the Drake gear I have, and was wondering if there is any thing in particular to watch for when upgrading to a 3 wire power cable to the Drake gear. I note that I had about a 90V difference between the chassis of my R4B and the T4XC and by reversing the receiver plug, that went away. I am hoping to do away with this problem by installing a keyed three wire cable to also add an AC ground to the system. Any thoughts about this? 73 Mike - K7OV
