[TenTec] location of r23 on final board in Jupiter

[mark kenward]

 Apparently, Gary Greene had said that you can bias finals and drivers in the Jupiter by measuring ,7 volts at r21 which is a stand up resistor and easily located, and r23 which I cannot locate.
Can someone tell me or show a picture where r23 is in the final compartment?
I have substitute drivers in the rig, but for the life of me I cannot locate r23
The transistor I am using is a 1945 which shows as a substitute and , hopefully, will put the Jupiter back on the air. 
Ten Tec sent it back because they cannot locate the proper 3133 drivers, therefore the rig is un repairable.
Thank you all for your help.
