So I have been working on the 610. I strung an ant. wire in my attic and stations are coming in pretty good. One issue I cannot figure out is on the broadcast band I can get plenty of stations from 550kh to the 1100kh range but  any higher I only get static. I can't figure out why. Also I did a voltage check on the tubes and here are the results. 6a7 p-249volts, sg-86v, k-.26v, g-134v.Type 78 p-294v, sg-86v, k-0v. type 75 p-184v, type 42 280v. There were some changes that were made that may account for the voltage differences.It is possible that the zero voltage on the 78 tube cathode is because my original wiring did not have a resistor tied to it and going to ground so I didn't install one and hooked directly to ground. Do these voltages look ok? Some seem high but I understand this might be because of higher supply voltage from the power company. Any checks I can make to fix the lack of stations on the higher broadcast band? Any help would be appreciated.
