Resistors used in Model 20
#16

Did the John Grady Interstage Transformer Mod described in the Library by Ron R and replaced the old replacement caps in my own Philco 20.  Big difference!  My friend's interstage is a total mess and is already bridged with an 0.033uF 200V cap without the 27K Ohm dropping resistor, so this is going to be redone properly.

In the process of replacing caps and resistors on my friend's 20.  All the blocks have been stuffed.  Unfortunately, all of those pretty resistors have to go, as they are all totally out of range.  Morzh was dead on correct as usual. Ron and all, thx for the resistor rating. I intend to use 1 watters or half wat paralleled as necessary. I wonder if they can be drilled on a hidden side to break the connections then solder replacement resistors hidden behind the originals.  the 2 500K jobs read about 5 meg, but I am afraid of them being noisy, and the "customer" (my friend) is not looking to have a pristine restoration of the chassis underside.

After that, I will break the connections inside the filter cap can and install new ones under the chassis.  My friend will be tasked with chassis rust and dirt cleanup, can polishing and painting.
