RESISTOR ID 38-15 philco help
#15

http://s1289.photobucket.com/user/TROG99...c.jpg.html

I have had some time to look at the 38_15. What I have found is #22 the 4 Meg is gone. A 7Meg to ground is on the cap side to Tube 75 that #22 the 4 Meg went to.

Further # 17 2Meg is gone. It looks like they split into two 1 Meg and attached a Cap in between.

Above picture is of the bottom side again. I went thru and I identified each component. I have a small idea of what they did. Just a lil foggy the 2 1 Meg connect. It was late so I have only tried to get a picture have changed nothing.

The 1 Meg attached to the TB reads 975K. It then attaches to the Switch #3 position A5-A7. This is where the switch is setting did not move it.

The other reads 1.1 Meg goes from Tube 75 pin 3 the junction point of the three components to pin 5.

The 7 Meg attaches to #21 Cap the side not attache to the 500k variable resistor #20 then goes to ground.

I am making a schematic to show were they attach. After looking at the 38-10 it does appear close to that configuration.

I have assumed that #3 is the A5-A7 because I did not see that on the electronic schematic just on the Bottom view.

I would like to make sure I'm not sitting near the bleachers in left field. I will at this point replace them one for one.
