Philco 610 Resisters Question
#1

i am working on a Philco 610 and have a couple of questions. Basic stuff for most of you but not for me. My radio adio appears to be a later run but I don’t know the actual run number. 

http://www.nostalgiaair.org/PagesByModel...013797.pdf

I read up on all the changes on the parts list with the three electrolytic #54, #56 and #41 as well as the change of #39 and #40 resisters.

In the photo of my radio, resister #40 is connected to bakelite block 15. I believe these are duo 19K resisters in parrallel, that calculate to 9.5K. The problem is, I think this should be a 25K resistor.  

Resistor #39 in my radio is duo 45K parrallel resisters that calculate to 22.5 K. My question is, should these two resisters be switched when I replace them and what wattage should I use? I have seen other photos of a 610 chassis and their 9K/10K dogbone resisters looked huge.

Resister #42 in the photo of my radio is a 25K and just looking to confirm that it should be a 32K. It connects to Pin 4 of the 6A7 and the 16 mfd electrolytic.

I do have one more question. Electrolytic #54 on my radio has the cardboard insulator on it but it’s negative connection goes to the CT on #57 resister. Am I reading this correctly? I thought that these insulating sleeves required you to connect to the tab on the side of the electrolytic and keep it isolated from the chassis.

Love this hobby but as you can tell...I’ve got a lot to learn. Any assistance is greatly appreciated!
