R102 300 ohm resistor

i recommend reading through my thread. .... it will save you time.


post 176,, your gut feeling is correct as was mine.  go with something you can relocate to the top side of the chassis where the tubes are.
R102 willl end up being calibrated to your radio but i found 600 ohms and 50 watts or more was needed to get the voltage at both 6k6's below 300v each **and** be able to let out the heat its going to generate..
I would be very interested if you were able to make a 10w 300ohm resistor work in this area.


post 160 is where i decided tto change to what was best.
post 127 shows that this R102 is directly underneath your 5y3,,, not a good place for such a "known issue" problem resistor.

your talking about a mix of AC & DC at this point in the circuit is correct. This is the resistor philco never "solved" and it was the one that was a "known issue".

big things i noticed and worked hard on....
-R102- many many hours solving this "known" problem that was never factory fixed for real.
-the filter caps downstream of the transformer but upstream of the 5y3 are incorrectly identified on the fold out schematic but once you red line this you will be fine.


asked earlier,,, what run number are you?  i assume run3.

there are no known diagrams of run3.

if you got prints from the philco workbench you will discover that ****************ONLY *********** the fold out schematic should be used to restore a run3 code 125. 
You have to combine Run1 and Run2 and Run3 ..
The diagrams from Chuck "philco work bench" will define all runs,, run1, run2 and run3.
when you bounce from each you will find out what i am saying.

f you have many question markes in your mind about the things you find odd,, this fold out schematic will help.

avoid using the schematics that are formed into a booklet so to speak.  those dont match a run3 code 125.

im at 304 772 3411 if you need to sanity check anything.

hopefully you are running a 7af7 on V1, if not you will smoke a replacement resistor you prob did on V1.... I did.
also my v1 was carbon flashed so before i had any locktal sockets, i took it apart , sanded the bakealite , flipped it over,,, did corrosion control on the pin then put it all back together. wish i had smaller rivits though, the oem ones were perfect and low profile.
