My resistor looks like this.
brown grey green black black brown.
From the Document.
"There was an issue discovered after several production runs in all the clean to mid-gain Randall models including the Clean, Blackface, DLX, Top Boost, Plexi, JTM, & Brown, that causes excess distortion overloading the input gain. Too eliminate this issue and clean up these modules, position R1 which is a 470 ohm 1/2w resistor, needs to be changed to a 150 Ohm 1/2w resistor. This is only the early production Randall models and some of the early Egnater models. The new modules have been fixed at the factory but you should check any current module that you have. You can identify what value is in your module by the color bands located on the resistor, 470 ohm resistors have yellow, purple, and brown color bands, where the correct 150 ohm resistors have brown, green, brown color bands"
So I have neither of these. What's up?
