Philco 60 code 121 IF's
#23

Not working yet. R10 I have a 50K, 4 caps make up #20 all changed the .09 are .1, .05 and a .5, Cap #13 is a new 110pf, a crossed pin #1 and #3.
On the 6A7 pin 4 you said 2-4 volts but the Philco 60 service bulletin shows it should be 180 volts I have 140 volts I changed the R10 from 32K to 27K to get more voltage. It was 102v.    
Remember this radio works on BC band.
Here is what I found, when the band switch is moved to SW the voltages drop.
On the osc coil this is what I found

BC band ------ SW band
Pin #1 22v ------- 3.3v
Pin #2 145v ------- 95v
Pin #3 149v ------- 95v
Pin #4 26 -------- 3.3v
Pin #5 26 ------- 3.3v
Top wire 22.9 ------ 3.3v

On the 6A7 voltages
BC Band ------ SW Band

Pin #2 255v ------ 254v
Pin #3 80v ------ 59v
Pin #4 140v ------ 92v
Pin #5 24v ------ .48v

These readings are from K #6 to pin

I have not tried another 6A7, I don't have a new one only used.
I have checked and rechecked wiring, but something is dropping the voltage when the band switch is in SW mode.
