The information above is jumbled together, so I'll try again:
Tube 84---pin no. 4(k)...202v
" 41--- " " . 2(a)...149v
. 3(g2)..160v
" 75--- " " . 2(a)...122v
" 78--- " " . 2(a)...162v
. 3(g2)..122v
" 6A7---" " . 2(a)...162v
. 3(g3+g5..122v
Sure, just wrap a wire around top connection of your 6A7 tube. It should connect to the antenna coil and tuner.
Your voltages are reasonable. Is pin #5 on your 6A7 negative a few volts? If pin #5 isn't negative the oscillator isn't operating. Check continuity of the oscillator coil. Philco had probems with corrosion on these coils.
Top cap of the 75 goes to second IF Transformer, 78 1st IF Transformer and 6A7 tuner. Do you hear loud hum touching top of the 75 tube?

::I started to work on this radio over the Holidays and soon ran into problems due to grid cap connectors being placed on wrong tubes, etc. by a previous owner. I can’t find a schematic but I’m using Philco 39-119 which seems to be close to this chassis. This radio has a volume controlled hum although the electrolytic capacitors are replaced….no stations either. Also, the connection is missing from grid cap 6A7 tube. Can I just use wire wrapped around the grid cap until I find a proper connector? I’m assuming that the grid cap of 6A7 tube connects to the antenna coil??

Touching the top of your 75 and hearing loud hum shows the audio circuit in you radio is operating.
Check the oscillator coil for continuity. This is a separate coil from the antenna. Pins #4, #5 and #6 make up the oscillator section of a 6A7 tube. The coil is marked #6 in the 119 schematic. It has 3 windings.
http://www.nostalgiaair.org/PagesByModel/271/M0013271.pdf
Looks like in this radio top cap of the 6A7 doesn't go dirctly to a tuner. It does go to coil #1 and switch #43 before going to the tuner. Does any push buttons operate on your radio?
Tune your Philco radio to 1000 KHz. Tune a second, close by, radio to 1470 KHz. You should be able to hear the oscillator signal. The osc signal will be 470 KHz above the frequency set on your Philco.
Norm
:Norm.....Thanks for your prompt reply. I checked voltage on pin 5 of 6A7 and got no reading...zero..However, I did get continuity between contacts on antenna coil. I'm still not receiving stations although I touched end of wire from grid cap of 6A7 to various points on coil plus the tuner. I'm sure you realize now that I don't have a clue as to where the wire from 6A7 is connected to on the antenna coil. For your information, when checking voltages a station would cut in when touching pin 2 of tube 78. Also, a loud hum when touching grid cap of tube 75. I'm not sure if any of this information tells you anything.
:All the best.

Pins 3 and 4 of the 75 should have very little voltage. Actual voltage on these pins should be near zero. It will vary slightly depending on signal strength.
This radio requires the first push button to be pressed in order to tune stations.
Norm
:Norm/Edd------Yes, this radio has push button tuning.Also, when checking oscillator with another radio the oscillator came in loud and clear. I am also receiving continuity between relative points on the antenna coils and oscillator. One question, I notice that another posting here says that pins 3 and 4 of tube 75 should receive the same voltages but I'm not receiving any voltages on these pins. I replaced tube 75 with another 75 tube and still no voltages on 3 and 4 pins....??????....still no stations...any ideas??

Temporary / permanent ? Plate – Grid cap connector……..Remember the old automotive HEAVY I turn coil spring wire clamp, or, them also being used on your washing machines drain hoses ?
And in a pinch, you would try to use common slip joint pliers to compress them and you would invariably get a PINCH…typically several of them…....industrial sized, blue-black blood blister categorized ones.... to be exact ! ! !
This is an painless electrical variant….
If you will dig thru your coil spring collection ( or seek and buy) and then you choose one with < ~ 3/8in I.D. loops( but.... didn't a 6A7 use a 1/4 in dia cap ?) and you can then cut off 3 coil links and uncoil from the 2 opposite ends to make the configuration as shown below.
Then you liberally flux up one connecting spring wire end and tin it up and then reflow solder your wire connection. Compress the tabs to flex open and slip the link over the tube cap and release, and the tube connection is firmly gripped..
